About php.ini  ;
PHP's initialization file, generally called php.ini, is responsible for
configuring many of the aspects of PHP's behavior.
PHP attempts to find and load this configuration from a number of locations.
The following is a summary of its search order
1. SAPI module specific location.
2. The PHPRC environment variable. (As of PHP 5.2.0)
3. A number of predefined registry keys on Windows (As of PHP 5.2.0)
4. Current working directory (except CLI)
5. The web server's directory (for SAPI modules), or directory of PHP
(otherwise in Windows)
6. The directory from the --with-config-file-path compile time option, or the
Windows directory (usually C
\windows)
See the PHP docs for more specific information.
http://php.net/configuration.file
The syntax of the file is extremely simple. Whitespace and lines
beginning with a semicolon are silently ignored (as you probably guessed).
Section headers (e.g. [Foo]) are also silently ignored, even though
they might mean something in the future.
Directives following the section heading [PATH=/www/mysite] only
apply to PHP files in the /www/mysite directory. Directives
following the section heading [HOST=www.example.com] only apply to
PHP files served from www.example.com. Directives set in these
special sections cannot be overridden by user-defined INI files or
at runtime. Currently, [PATH=] and [HOST=] sections only work under
CGI/FastCGI.
http://php.net/ini.sections
Directives are specified using the following syntax
directive = value
Directive names are *case sensitive* - foo=bar is different from FOO=bar.
Directives are variables used to configure PHP or PHP extensions.
There is no name validation. If PHP can't find an expected
directive because it is not set or is mistyped, a default value will be used.
The value can be a string, a number, a PHP constant (e.g. E_ALL or M_PI), one
of the INI constants (On, Off, True, False, Yes, No and None) or an expression
(e.g. E_ALL & ~E_NOTICE), a quoted string ("bar"), or a reference to a
previously set variable or directive (e.g. ${foo})
Expressions in the INI file are limited to bitwise operators and parentheses
| bitwise OR
^ bitwise XOR
& bitwise AND
~ bitwise NOT
! boolean NOT
Boolean flags can be turned on using the values 1, On, True or Yes.
They can be turned off using the values 0, Off, False or No.
An empty string can be denoted by simply not writing anything after the equal
sign, or by using the None keyword
foo =  ; sets foo to an empty string
foo = None  ; sets foo to an empty string
foo = "None"  ; sets foo to the string 'None'
If you use constants in your value, and these constants belong to a
dynamically loaded extension (either a PHP extension or a Zend extension),
you may only use these constants *after* the line that loads the extension.
About this file ;
PHP comes packaged with two INI files. One that is recommended to be used
in production environments and one that is recommended to be used in
development environments.
php.ini-production contains settings which hold security, performance and
best practices at its core. But please be aware, these settings may break
compatibility with older or less security conscience applications. We
recommending using the production ini in production and testing environments.
php.ini-development is very similar to its production variant, except it is
much more verbose when it comes to errors. We recommend using the
development version only in development environments, as errors shown to
application users can inadvertently leak otherwise secure information.
This is the php.ini-production INI file.
Quick Reference ;
The following are all the settings which are different in either the production
or development versions of the INIs with respect to PHP's default behavior.
Please see the actual settings later in the document for more details as to why
we recommend these changes in PHP's behavior.

php.ini Options  ;
Name for user-defined php.ini (.htaccess) files. Default is ".user.ini"
user_ini.filename = ".user.ini"
To disable this feature set this option to an empty value
user_ini.filename =
TTL for user-defined php.ini files (time-to-live) in seconds. Default is 300 seconds (5 minutes)
user_ini.cache_ttl = 300
Language Options ;
Enable the PHP scripting language engine under Apache.
http://php.net/engine

This directive determines whether or not PHP will recognize code between
<? and ?> tags as PHP source which should be processed as such. It is
generally recommended that <?php and ?> should be used and that this feature
should be disabled, as enabling it may result in issues when generating XML
documents, however this remains supported for backward compatibility reasons.
Note that this directive does not control the <?= shorthand tag, which can be
used regardless of this directive.
Default Value
On
Development Value
Off
Production Value
Off
http://php.net/short-open-tag

short_open_tag = On

The number of significant digits displayed in floating point numbers.
http://php.net/precision

precision = 14

Output buffering is a mechanism for controlling how much output data
(excluding headers and cookies) PHP should keep internally before pushing that
data to the client. If your application's output exceeds this setting, PHP
will send that data in chunks of roughly the size you specify.
Turning on this setting and managing its maximum buffer size can yield some
interesting side-effects depending on your application and web server.
You may be able to send headers and cookies after you've already sent output
through print or echo. You also may see performance benefits if your server is
emitting less packets due to buffered output versus PHP streaming the output
as it gets it. On production servers, 4096 bytes is a good setting for performance
reasons.
Note
Output buffering can also be controlled via Output Buffering Control
functions.
Possible Values
On = Enabled and buffer is unlimited. (Use with caution)
Off = Disabled
Integer = Enables the buffer and sets its maximum size in bytes.
Note
This directive is hardcoded to Off for the CLI SAPI
Default Value
Off
Development Value
4096
Production Value
4096
http://php.net/output-buffering

output_buffering = 4096

You can redirect all of the output of your scripts to a function. For
example, if you set output_handler to "mb_output_handler", character
encoding will be transparently converted to the specified encoding.
Setting any output handler automatically turns on output buffering.
Note
People who wrote portable scripts should not depend on this ini
directive. Instead, explicitly set the output handler using ob_start().
Using this ini directive may cause problems unless you know what script
is doing.
Note
You cannot use both "mb_output_handler" with "ob_iconv_handler"
and you cannot use both "ob_gzhandler" and "zlib.output_compression".
Note
output_handler must be empty if this is set 'On' !!!!
Instead you must use zlib.output_handler.
http://php.net/output-handler
output_handler =
URL rewriter function rewrites URL on the fly by using
output buffer. You can set target tags by this configuration.
"form" tag is special tag. It will add hidden input tag to pass values.
Refer to session.trans_sid_tags for usage.
Default Value
"form="
Development Value
"form="
Production Value
"form="
url_rewriter.tags
URL rewriter will not rewrite absolute URL nor form by default. To enable
absolute URL rewrite, allowed hosts must be defined at RUNTIME.
Refer to session.trans_sid_hosts for more details.
Default Value
""
Development Value
""
Production Value
""
url_rewriter.hosts
Transparent output compression using the zlib library
Valid values for this option are 'off', 'on', or a specific buffer size
to be used for compression (default is 4KB)
Note
Resulting chunk size may vary due to nature of compression. PHP
outputs chunks that are few hundreds bytes each as a result of
compression. If you prefer a larger chunk size for better
performance, enable output_buffering in addition.
Note
You need to use zlib.output_handler instead of the standard
output_handler, or otherwise the output will be corrupted.
http://php.net/zlib.output-compression

zlib.output_compression = Off

http://php.net/zlib.output-compression-level
zlib.output_compression_level = -1
You cannot specify additional output handlers if zlib.output_compression
is activated here. This setting does the same as output_handler but in
a different order.
http://php.net/zlib.output-handler
zlib.output_handler =
Implicit flush tells PHP to tell the output layer to flush itself
automatically after every output block. This is equivalent to calling the
PHP function flush() after each and every call to print() or echo() and each
and every HTML block. Turning this option on has serious performance
implications and is generally recommended for debugging purposes only.
http://php.net/implicit-flush
Note
This directive is hardcoded to On for the CLI SAPI

implicit_flush = Off

The unserialize callback function will be called (with the undefined class'
name as parameter), if the unserializer finds an undefined class
which should be instantiated. A warning appears if the specified function is
not defined, or if the function doesn't include/implement the missing class.
So only set this entry, if you really want to implement such a
callback-function.

unserialize_callback_func =

The unserialize_max_depth specifies the default depth limit for unserialized
structures. Setting the depth limit too high may result in stack overflows
during unserialization. The unserialize_max_depth ini setting can be
overridden by the max_depth option on individual unserialize() calls.
A value of 0 disables the depth limit.
unserialize_max_depth = 4096
When floats & doubles are serialized, store serialize_precision significant
digits after the floating point. The default value ensures that when floats
are decoded with unserialize, the data will remain the same.
The value is also used for json_encode when encoding double values.
If -1 is used, then dtoa mode 0 is used which automatically select the best
precision.

serialize_precision = -1

open_basedir, if set, limits all file operations to the defined directory
and below. This directive makes most sense if used in a per-directory
or per-virtualhost web server configuration file.
Note
disables the realpath cache
http://php.net/open-basedir
open_basedir =
This directive allows you to disable certain functions.
It receives a comma-delimited list of function names.
http://php.net/disable-functions

disable_functions =

This directive allows you to disable certain classes.
It receives a comma-delimited list of class names.
http://php.net/disable-classes

disable_classes =

Colors for Syntax Highlighting mode. Anything that's acceptable in
would work.
http://php.net/syntax-highlighting
highlight.string = #DD0000
highlight.comment = #FF9900
highlight.keyword = #007700
highlight.default = #0000BB
highlight.html = #000000
If enabled, the request will be allowed to complete even if the user aborts
the request. Consider enabling it if executing long requests, which may end up
being interrupted by the user or a browser timing out. PHP's default behavior
is to disable this feature.
http://php.net/ignore-user-abort
ignore_user_abort = On
Determines the size of the realpath cache to be used by PHP. This value should
be increased on systems where PHP opens many files to reflect the quantity of
the file operations performed.
Note
if open_basedir is set, the cache is disabled
http://php.net/realpath-cache-size
realpath_cache_size = 4096k
Duration of time, in seconds for which to cache realpath information for a given
file or directory. For systems with rarely changing files, consider increasing this
value.
http://php.net/realpath-cache-ttl
realpath_cache_ttl = 120
Enables or disables the circular reference collector.
http://php.net/zend.enable-gc

zend.enable_gc = On

If enabled, scripts may be written in encodings that are incompatible with
the scanner. CP936, Big5, CP949 and Shift_JIS are the examples of such
encodings. To use this feature, mbstring extension must be enabled.
zend.multibyte = Off
Allows to set the default encoding for the scripts. This value will be used
unless "declare(encoding=...)" directive appears at the top of the script.
Only affects if zend.multibyte is set.
zend.script_encoding =
Allows to include or exclude arguments from stack traces generated for exceptions.
In production, it is recommended to turn this setting on to prohibit the output
of sensitive information in stack traces
Default Value
Off
Development Value
Off
Production Value
On

zend.exception_ignore_args = On

Allows setting the maximum string length in an argument of a stringified stack trace
to a value between 0 and 1000000.
This has no effect when zend.exception_ignore_args is enabled.
Default Value
15
Development Value
15
Production Value
0
In production, it is recommended to set this to 0 to reduce the output
of sensitive information in stack traces.

zend.exception_string_param_max_len = 0

Miscellaneous ;
Decides whether PHP may expose the fact that it is installed on the server
(e.g. by adding its signature to the Web server header). It is no security
threat in any way, but it makes it possible to determine whether you use PHP
on your server or not.
http://php.net/expose-php

expose_php = Off

Resource Limits ;
Maximum execution time of each script, in seconds
http://php.net/max-execution-time
Note
This directive is hardcoded to 0 for the CLI SAPI

max_execution_time = 120

Maximum amount of time each script may spend parsing request data. It's a good
idea to limit this time on productions servers in order to eliminate unexpectedly
long running scripts.
Note
This directive is hardcoded to -1 for the CLI SAPI
Default Value
-1 (Unlimited)
Development Value
60 (60 seconds)
Production Value
60 (60 seconds)
http://php.net/max-input-time

max_input_time = 60

Maximum input variable nesting level
http://php.net/max-input-nesting-level
max_input_nesting_level = 64
How many GET/POST/COOKIE input variables may be accepted

max_input_vars = 20000

Maximum amount of memory a script may consume
http://php.net/memory-limit

memory_limit = 128M

Error handling and logging ;
This directive informs PHP of which errors, warnings and notices you would like
it to take action for. The recommended way of setting values for this
directive is through the use of the error level constants and bitwise
operators. The error level constants are below here for convenience as well as
some common settings and their meanings.
By default, PHP is set to take action on all errors, notices and warnings EXCEPT
those related to E_NOTICE and E_STRICT, which together cover best practices and
recommended coding standards in PHP. For performance reasons, this is the
recommend error reporting setting. Your production server shouldn't be wasting
resources complaining about best practices and coding standards. That's what
development servers and development settings are for.
Note
The php.ini-development file has this setting as E_ALL. This
means it pretty much reports everything which is exactly what you want during
development and early testing.
Error Level Constants
E_ALL - All errors and warnings (includes E_STRICT as of PHP 5.4.0)
E_ERROR - fatal run-time errors
E_RECOVERABLE_ERROR - almost fatal run-time errors
E_WARNING - run-time warnings (non-fatal errors)
E_PARSE - compile-time parse errors
E_NOTICE - run-time notices (these are warnings which often result
from a bug in your code, but it's possible that it was
intentional (e.g., using an uninitialized variable and
relying on the fact it is automatically initialized to an
empty string)
E_STRICT - run-time notices, enable to have PHP suggest changes
to your code which will ensure the best interoperability
and forward compatibility of your code
E_CORE_ERROR - fatal errors that occur during PHP's initial startup
E_CORE_WARNING - warnings (non-fatal errors) that occur during PHP's
initial startup
E_COMPILE_ERROR - fatal compile-time errors
E_COMPILE_WARNING - compile-time warnings (non-fatal errors)
E_USER_ERROR - user-generated error message
E_USER_WARNING - user-generated warning message
E_USER_NOTICE - user-generated notice message
E_DEPRECATED - warn about code that will not work in future versions
of PHP
E_USER_DEPRECATED - user-generated deprecation warnings
Common Values
E_ALL (Show all errors, warnings and notices including coding standards.)
E_ALL & ~E_NOTICE (Show all errors, except for notices)
E_ALL & ~E_NOTICE & ~E_STRICT (Show all errors, except for notices and coding standards warnings.)
E_COMPILE_ERROR|E_RECOVERABLE_ERROR|E_ERROR|E_CORE_ERROR (Show only errors)
Default Value
E_ALL
Development Value
E_ALL
Production Value
E_ALL & ~E_DEPRECATED & ~E_STRICT
http://php.net/error-reporting

error_reporting = E_ALL & ~E_DEPRECATED & ~E_STRICT

This directive controls whether or not and where PHP will output errors,
notices and warnings too. Error output is very useful during development, but
it could be very dangerous in production environments. Depending on the code
which is triggering the error, sensitive information could potentially leak
out of your application such as database usernames and passwords or worse.
For production environments, we recommend logging errors rather than
sending them to STDOUT.
Possible Values
Off = Do not display any errors
stderr = Display errors to STDERR (affects only CGI/CLI binaries!)
On or stdout = Display errors to STDOUT
Default Value
On
Development Value
On
Production Value
Off
http://php.net/display-errors

display_errors = Off

The display of errors which occur during PHP's startup sequence are handled
separately from display_errors. We strongly recommend you set this to 'off'
for production servers to avoid leaking configuration details.
Default Value
On
Development Value
On
Production Value
Off
http://php.net/display-startup-errors

display_startup_errors = Off

Besides displaying errors, PHP can also log errors to locations such as a
server-specific log, STDERR, or a location specified by the error_log
directive found below. While errors should not be displayed on productions
servers they should still be monitored and logging is a great way to do that.
Default Value
Off
Development Value
On
Production Value
On
http://php.net/log-errors

log_errors = On

Set maximum length of log_errors. In error_log information about the source is
added. The default is 1024 and 0 allows to not apply any maximum length at all.
http://php.net/log-errors-max-len

log_errors_max_len = 1024

Do not log repeated messages. Repeated errors must occur in same file on same
line unless ignore_repeated_source is set true.
http://php.net/ignore-repeated-errors

ignore_repeated_errors = Off

Ignore source of message when ignoring repeated messages. When this setting
is On you will not log errors with repeated messages from different files or
source lines.
http://php.net/ignore-repeated-source

ignore_repeated_source = Off

If this parameter is set to Off, then memory leaks will not be shown (on
stdout or in the log). This is only effective in a debug compile, and if
error reporting includes E_WARNING in the allowed list
http://php.net/report-memleaks

report_memleaks = On

This setting is off by default.
report_zend_debug = 0
Turn off normal error reporting and emit XML-RPC error XML
http://php.net/xmlrpc-errors
xmlrpc_errors = 0
An XML-RPC faultCode
xmlrpc_error_number = 0
When PHP displays or logs an error, it has the capability of formatting the
error message as HTML for easier reading. This directive controls whether
the error message is formatted as HTML or not.
Note
This directive is hardcoded to Off for the CLI SAPI
http://php.net/html-errors
html_errors = On
If html_errors is set to On *and* docref_root is not empty, then PHP
produces clickable error messages that direct to a page describing the error
or function causing the error in detail.
You can download a copy of the PHP manual from http://php.net/docs
and change docref_root to the base URL of your local copy including the
leading '/'. You must also specify the file extension being used including
the dot. PHP's default behavior is to leave these settings empty, in which
case no links to documentation are generated.
Note
Never use this feature for production boxes.
http://php.net/docref-root
Examples
docref_root = "/phpmanual/"
http://php.net/docref-ext
docref_ext = .html
String to output before an error message. PHP's default behavior is to leave
this setting blank.
http://php.net/error-prepend-string
Example
error_prepend_string = ""
String to output after an error message. PHP's default behavior is to leave
this setting blank.
http://php.net/error-append-string
Example
error_append_string = ""
Log errors to specified file. PHP's default behavior is to leave this value
empty.
http://php.net/error-log
Example
error_log = php_errors.log
Log errors to syslog (Event Log on Windows).
error_log = syslog
The syslog ident is a string which is prepended to every message logged
to syslog. Only used when error_log is set to syslog.
syslog.ident = php
The syslog facility is used to specify what type of program is logging
the message. Only used when error_log is set to syslog.
syslog.facility = user
Set this to disable filtering control characters (the default).
Some loggers only accept NVT-ASCII, others accept anything that's not
control characters. If your logger accepts everything, then no filtering
is needed at all.
Allowed values are
ascii (all printable ASCII characters and NL)
no-ctrl (all characters except control characters)
all (all characters)
raw (like "all", but messages are not split at newlines)
http://php.net/syslog.filter
syslog.filter = ascii
windows.show_crt_warning
Default value
0
Development value
0
Production value
0
Data Handling ;
The separator used in PHP generated URLs to separate arguments.
PHP's default setting is "&".
http://php.net/arg-separator.output
Example
arg_separator.output = "&"
List of separator(s) used by PHP to parse input URLs into variables.
PHP's default setting is "&".
NOTE
Every character in this directive is considered as separator!
http://php.net/arg-separator.input
Example
arg_separator.input = ";&"
This directive determines which super global arrays are registered when PHP
starts up. G,P,C,E & S are abbreviations for the following respective super
globals
GET, POST, COOKIE, ENV and SERVER. There is a performance penalty
paid for the registration of these arrays and because ENV is not as commonly
used as the others, ENV is not recommended on productions servers. You
can still get access to the environment variables through getenv() should you
need to.
Default Value
"EGPCS"
Development Value
"GPCS"
Production Value
"GPCS";
http://php.net/variables-order

variables_order = "GPCS"

This directive determines which super global data (G,P & C) should be
registered into the super global array REQUEST. If so, it also determines
the order in which that data is registered. The values for this directive
are specified in the same manner as the variables_order directive,
EXCEPT one. Leaving this value empty will cause PHP to use the value set
in the variables_order directive. It does not mean it will leave the super
globals array REQUEST empty.
Default Value
None
Development Value
"GP"
Production Value
"GP"
http://php.net/request-order

request_order = "GP"

This directive determines whether PHP registers $argv & $argc each time it
runs. $argv contains an array of all the arguments passed to PHP when a script
is invoked. $argc contains an integer representing the number of arguments
that were passed when the script was invoked. These arrays are extremely
useful when running scripts from the command line. When this directive is
enabled, registering these variables consumes CPU cycles and memory each time
a script is executed. For performance reasons, this feature should be disabled
on production servers.
Note
This directive is hardcoded to On for the CLI SAPI
Default Value
On
Development Value
Off
Production Value
Off
http://php.net/register-argc-argv

register_argc_argv = Off

When enabled, the ENV, REQUEST and SERVER variables are created when they're
first used (Just In Time) instead of when the script starts. If these
variables are not used within a script, having this directive on will result
in a performance gain. The PHP directive register_argc_argv must be disabled
for this directive to have any effect.
http://php.net/auto-globals-jit

auto_globals_jit = On

Whether PHP will read the POST data.
This option is enabled by default.
Most likely, you won't want to disable this option globally. It causes $_POST
and $_FILES to always be empty; the only way you will be able to read the
POST data will be through the php
//input stream wrapper. This can be useful
to proxy requests or to process the POST data in a memory efficient fashion.
http://php.net/enable-post-data-reading
enable_post_data_reading = Off
Maximum size of POST data that PHP will accept.
Its value may be 0 to disable the limit. It is ignored if POST data reading
is disabled through enable_post_data_reading.
http://php.net/post-max-size

post_max_size = 50M

Automatically add files before PHP document.
http://php.net/auto-prepend-file

auto_prepend_file =

Automatically add files after PHP document.
http://php.net/auto-append-file

auto_append_file =

By default, PHP will output a media type using the Content-Type header. To
disable this, simply set it to be empty.
PHP's built-in default media type is set to text/html.
http://php.net/default-mimetype

default_mimetype = "text/html"

PHP's default character set is set to UTF-8.
http://php.net/default-charset

default_charset = "UTF-8"

PHP internal character encoding is set to empty.
If empty, default_charset is used.
http://php.net/internal-encoding
internal_encoding =
PHP input character encoding is set to empty.
If empty, default_charset is used.
http://php.net/input-encoding
input_encoding =
PHP output character encoding is set to empty.
If empty, default_charset is used.
See also output_buffer.
http://php.net/output-encoding
output_encoding =
Paths and Directories ;
UNIX
"/path1:/path2"
include_path = ".
/php/includes"
Windows
"\path1;\path2"
include_path = ".;c
\php\includes"
PHP's default setting for include_path is ".;/path/to/php/pear"
http://php.net/include-path
The root of the PHP pages, used only if nonempty.
if PHP was not compiled with FORCE_REDIRECT, you SHOULD set doc_root
if you are running php as a CGI under any web server (other than IIS)
see documentation for security issues. The alternate is to use the
cgi.force_redirect configuration below
http://php.net/doc-root

doc_root =

The directory under which PHP opens the script using /~username used only
if nonempty.
http://php.net/user-dir

user_dir =

Directory in which the loadable extensions (modules) reside.
http://php.net/extension-dir
extension_dir = "./"
On windows
extension_dir = "ext"
Directory where the temporary files should be placed.
Defaults to the system default (see sys_get_temp_dir)
sys_temp_dir = "/tmp"
Whether or not to enable the dl() function. The dl() function does NOT work
properly in multithreaded servers, such as IIS or Zeus, and is automatically
disabled on them.
http://php.net/enable-dl

enable_dl = Off

cgi.force_redirect is necessary to provide security running PHP as a CGI under
most web servers. Left undefined, PHP turns this on by default. You can
turn it off here AT YOUR OWN RISK
**You CAN safely turn this off for IIS, in fact, you MUST.**
http://php.net/cgi.force-redirect
cgi.force_redirect = 1
if cgi.nph is enabled it will force cgi to always sent Status
200 with
every request. PHP's default behavior is to disable this feature.
cgi.nph = 1
if cgi.force_redirect is turned on, and you are not running under Apache or Netscape
(iPlanet) web servers, you MAY need to set an environment variable name that PHP
will look for to know it is OK to continue execution. Setting this variable MAY
cause security issues, KNOW WHAT YOU ARE DOING FIRST.
http://php.net/cgi.redirect-status-env
cgi.redirect_status_env =
cgi.fix_pathinfo provides *real* PATH_INFO/PATH_TRANSLATED support for CGI. PHP's
previous behaviour was to set PATH_TRANSLATED to SCRIPT_FILENAME, and to not grok
what PATH_INFO is. For more information on PATH_INFO, see the cgi specs. Setting
this to 1 will cause PHP CGI to fix its paths to conform to the spec. A setting
of zero causes PHP to behave as before. Default is 1. You should fix your scripts
to use SCRIPT_FILENAME rather than PATH_TRANSLATED.
http://php.net/cgi.fix-pathinfo
cgi.fix_pathinfo=1
if cgi.discard_path is enabled, the PHP CGI binary can safely be placed outside
of the web tree and people will not be able to circumvent .htaccess security.
cgi.discard_path=1
FastCGI under IIS supports the ability to impersonate
security tokens of the calling client. This allows IIS to define the
security context that the request runs under. mod_fastcgi under Apache
does not currently support this feature (03/17/2002)
Set to 1 if running under IIS. Default is zero.
http://php.net/fastcgi.impersonate
fastcgi.impersonate = 1
Disable logging through FastCGI connection. PHP's default behavior is to enable
this feature.
fastcgi.logging = 0
cgi.rfc2616_headers configuration option tells PHP what type of headers to
use when sending HTTP response code. If set to 0, PHP sends Status
header that
is supported by Apache. When this option is set to 1, PHP will send
RFC2616 compliant header.
Default is zero.
http://php.net/cgi.rfc2616-headers
cgi.rfc2616_headers = 0
cgi.check_shebang_line controls whether CGI PHP checks for line starting with #!
(shebang) at the top of the running script. This line might be needed if the
script support running both as stand-alone script and via PHP CGI<. PHP in CGI
mode skips this line and ignores its content if this directive is turned on.

default_socket_timeout = 60

If your scripts have to deal with files from Macintosh systems,
or you are running on a Mac and need to deal with files from
unix or win32 systems, setting this flag will cause PHP to
automatically detect the EOL character in those files so that
fgets() and file() will work regardless of the source of the file.
http://php.net/auto-detect-line-endings
auto_detect_line_endings = Off
Dynamic Extensions ;
If you wish to have an extension loaded automatically, use the following
syntax
extension=modulename
For example
extension=mysqli
When the extension library to load is not located in the default extension
directory, You may specify an absolute path to the library file
extension=/path/to/extension/mysqli.so
Note
The syntax used in previous PHP versions ('extension=<ext>.so' and
'extension='php_<ext>.dll') is supported for legacy reasons and may be
deprecated in a future PHP major version. So, when it is possible, please
move to the new ('extension=<ext>) syntax.
Notes for Windows environments
- Many DLL files are located in the extensions/ (PHP 4) or ext/ (PHP 5+)
extension folders as well as the separate PECL DLL download (PHP 5+).
Be sure to appropriately set the extension_dir directive.

[Session]

Handler used to store/retrieve data.
http://php.net/session.save-handler

session.save_handler = files

Argument passed to save_handler. In the case of files, this is the path
where data files are stored. Note
Windows users have to change this
variable in order to use PHP's session functions.
The path can be defined as
session.save_path = "N;/path"
where N is an integer. Instead of storing all the session files in
/path, what this will do is use subdirectories N-levels deep, and
store the session data in those directories. This is useful if
your OS has problems with many files in one directory, and is
a more efficient layout for servers that handle many sessions.
NOTE 1
PHP will not create this directory structure automatically.
You can use the script in the ext/session dir for that purpose.
NOTE 2
See the section on garbage collection below if you choose to
use subdirectories for session storage
The file storage module creates files using mode 600 by default.
You can change that by using
session.save_path = "N;MODE;/path"
where MODE is the octal representation of the mode. Note that this
does not overwrite the process's umask.
http://php.net/session.save-path

session.save_path = "/var/lib/php/session"

Whether to use strict session mode.
Strict session mode does not accept an uninitialized session ID, and
regenerates the session ID if the browser sends an uninitialized session ID.
Strict mode protects applications from session fixation via a session adoption
vulnerability. It is disabled by default for maximum compatibility, but
enabling it is encouraged.
https://wiki.php.net/rfc/strict_sessions

session.use_strict_mode = 0

Whether to use cookies.
http://php.net/session.use-cookies

session.use_cookies = 1

http://php.net/session.cookie-secure
session.cookie_secure =
This option forces PHP to fetch and use a cookie for storing and maintaining
the session id. We encourage this operation as it's very helpful in combating
session hijacking when not specifying and managing your own session id. It is
not the be-all and end-all of session hijacking defense, but it's a good start.
http://php.net/session.use-only-cookies

session.use_only_cookies = 1

Name of the session (used as cookie name).
http://php.net/session.name

session.name = PHPSESSID

Initialize session on request startup.

http://php.net/session.cookie-path

session.cookie_path = /

The domain for which the cookie is valid.
http://php.net/session.cookie-domain

session.cookie_domain =

Whether or not to add the httpOnly flag to the cookie, which makes it
inaccessible to browser scripting languages such as JavaScript.
http://php.net/session.cookie-httponly

session.cookie_httponly =

Add SameSite attribute to cookie to help mitigate Cross-Site Request Forgery (CSRF/XSRF)
Current valid values are "Strict", "Lax" or "None". When using "None",
make sure to include the quotes, as `none` is interpreted like `false` in ini files.
https://tools.ietf.org/html/draft-west-first-party-cookies-07

session.cookie_samesite =

Handler used to serialize data. php is the standard serializer of PHP.
http://php.net/session.serialize-handler

session.serialize_handler = php

Defines the probability that the 'garbage collection' process is started on every
session initialization. The probability is calculated by using gc_probability/gc_divisor,
e.g. 1/100 means there is a 1% chance that the GC process starts on each request.
Default Value
1
Development Value
1
Production Value
1
http://php.net/session.gc-probability

session.gc_probability = 0

Defines the probability that the 'garbage collection' process is started on every
session initialization. The probability is calculated by using gc_probability/gc_divisor,
e.g. 1/100 means there is a 1% chance that the GC process starts on each request.
For high volume production servers, using a value of 1000 is a more efficient approach.
Default Value
100
Development Value
1000
Production Value
1000
http://php.net/session.gc-divisor

session.gc_divisor = 1000

After this number of seconds, stored data will be seen as 'garbage' and
cleaned up by the garbage collection process.
http://php.net/session.gc-maxlifetime

session.gc_maxlifetime = 1440

NOTE
If you are using the subdirectory option for storing session files
(see session.save_path above), then garbage collection does *not*
happen automatically. You will need to do your own garbage
collection through a shell script, cron entry, or some other method.
For example, the following script is the equivalent of setting
session.gc_maxlifetime to 1440 (1440 seconds = 24 minutes)
find /path/to/sessions -cmin +24 -type f | xargs rm
Check HTTP Referer to invalidate externally stored URLs containing ids.
HTTP_REFERER has to contain this substring for the session to be
considered as valid.

in publicly accessible computer.
- User may access your site with the same session ID
always using URL stored in browser's history or bookmarks.
http://php.net/session.use-trans-sid

session.use_trans_sid = 0

32
Development Value
26
Production Value
26

session.sid_length = 26

The URL rewriter will look for URLs in a defined set of HTML tags.
<form> is special; if you include them here, the rewriter will
add a hidden <input> field with the info which is otherwise appended
to URLs. <form> tag's action attribute URL will not be modified
unless it is specified.
Note that all valid entries require a "=", even if no value follows.
Default Value
"a=href,area=href,frame=src,form="
Development Value
"a=href,area=href,frame=src,form="
Production Value
"a=href,area=href,frame=src,form="
http://php.net/url-rewriter.tags

session.trans_sid_tags = "a=href,area=href,frame=src,form="

URL rewriter does not rewrite absolute URLs by default.
To enable rewrites for absolute paths, target hosts must be specified
at RUNTIME. i.e. use ini_set()
<form> tags is special. PHP will check action attribute's URL regardless
of session.trans_sid_tags setting.
If no host is defined, HTTP_HOST will be used for allowed host.
Example value
php.net,www.php.net,wiki.php.net
Use "," for multiple hosts. No spaces are allowed.

Only numbers between 200 and 1000000 are allowed.
opcache.max_accelerated_files=10000
The maximum percentage of "wasted" memory until a restart is scheduled.
opcache.max_wasted_percentage=5
When this directive is enabled, the OPcache appends the current working
directory to the script key, thus eliminating possible collisions between
files with the same name (basename). Disabling the directive improves
performance, but may break existing applications.
opcache.use_cwd=1
When disabled, you must reset the OPcache manually or restart the
webserver for changes to the filesystem to take effect.
opcache.validate_timestamps=1
How often (in seconds) to check file timestamps for changes to the shared
memory storage allocation. ("1" means validate once per second, but only
once per request. "0" means always validate)
opcache.revalidate_freq=2
Enables or disables file search in include_path optimization
opcache.revalidate_path=0
If disabled, all PHPDoc comments are dropped from the code to reduce the
size of the optimized code.
opcache.save_comments=1
If enabled, compilation warnings (including notices and deprecations) will
be recorded and replayed each time a file is included. Otherwise, compilation
warnings will only be emitted when the file is first cached.

Allow file existence override (file_exists, etc.) performance feature.
opcache.enable_file_override=0
A bitmask, where each bit enables or disables the appropriate OPcache
passes
opcache.optimization_level=0x7FFFBFFF
opcache.dups_fix=0
The location of the OPcache blacklist file (wildcards allowed).
Each OPcache blacklist file is a text file that holds the names of files
that should not be accelerated. The file format is to add each filename
to a new line. The filename may be a full path or just a file prefix
(i.e., /var/www/x blacklists all the files and directories in /var/www
that start with 'x'). Line starting with a ; are ignored (comments).
opcache.blacklist_filename=
Allows exclusion of large files from being cached. By default all files
are cached.
opcache.max_file_size=0
Check the cache checksum each N requests.
The default value of "0" means that the checks are disabled.
opcache.consistency_checks=0
How long to wait (in seconds) for a scheduled restart to begin if the cache
is not being accessed.
opcache.force_restart_timeout=180
OPcache error_log file name. Empty string assumes "stderr".
opcache.error_log=
All OPcache errors go to the Web server log.
By default, only fatal errors (level 0) or errors (level 1) are logged.
You can also enable warnings (level 2), info messages (level 3) or
debug messages (level 4).
opcache.log_verbosity_level=1

processes have to map shared memory into the same address space. This
directive allows to manually fix the "Unable to reattach to base address"
errors.
opcache.mmap_base=
Facilitates multiple OPcache instances per user (for Windows only). All PHP
processes with the same cache ID and user share an OPcache instance.
opcache.cache_id=
Enables and sets the second level cache directory.
It should improve performance when SHM memory is full, at server restart or
SHM reset. The default "" disables file based caching.
opcache.file_cache=
Enables or disables opcode caching in shared memory.
opcache.file_cache_only=0
Enables or disables checksum validation when script loaded from file cache.
opcache.file_cache_consistency_checks=1
Implies opcache.file_cache_only=1 for a certain process that failed to
reattach to the shared memory (for Windows only). Explicitly enabled file
cache is required.
opcache.file_cache_fallback=1

facilitates to let the preloading to be run as another user.
http://php.net/opcache.preload_user
opcache.preload_user=
Prevents caching files that are less than this number of seconds old. It
protects from caching of incompletely updated files. In case all file updates
on your site are atomic, you may increase performance by setting it to "0".
opcache.file_update_protection=2
Absolute path used to store shared lockfiles (for *nix only).
opcache.lockfile_path=/tmp

[curl]

A default value for the CURLOPT_CAINFO option. This is required to be an
absolute path.
curl.cainfo =

[openssl]

The location of a Certificate Authority (CA) file on the local filesystem
to use when verifying the identity of SSL/TLS peers. Most users should
not specify a value for this directive as PHP will attempt to use the
OS-managed cert stores in its absence. If specified, this value may still
be overridden on a per-stream basis via the "cafile" SSL stream context
option.
openssl.cafile=
If openssl.cafile is not specified or if the CA file is not found, the
directory pointed to by openssl.capath is searched for a suitable
certificate. This value must be a correctly hashed certificate directory.
Most users should not specify a value for this directive as PHP will
attempt to use the OS-managed cert stores in its absence. If specified,
this value may still be overridden on a per-stream basis via the "capath"
