The configuration file ( php.ini ) is read when PHP starts up. For the server module versions of PHP, this happens only once when the web server is started. For the CGI and CLI versions, it happens on every invocation.

SAPI module specific location ( PHPIniDir directive in Apache 2, -c command line option in CGI and CLI)
The PHPRC environment variable.
The location of the php.ini file can be set for different versions of PHP. The root of the registry keys depends on 32- or 64-bitness of the installed OS and PHP. For 32-bit PHP on a 32-bit OS or a 64-bit PHP on a 64-bit OS use [(HKEY_LOCAL_MACHINE\SOFTWARE\PHP] for 32-bit version of PHP on a 64-bit OS use [HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\PHP] ] instead. For same bitness installation the following registry keys are examined in order: [HKEY_LOCAL_MACHINE\SOFTWARE\PHP\x.y.z] , [HKEY_LOCAL_MACHINE\SOFTWARE\PHP\x.y] and [HKEY_LOCAL_MACHINE\SOFTWARE\PHP\x] , where x, y and z mean the PHP major, minor and release versions. For 32 bit versions of PHP on a 64 bit OS the following registry keys are examined in order: [HKEY_LOCAL_MACHINE\SOFTWARE\WOW6421Node\PHP\x.y.z] , [HKEY_LOCAL_MACHINE\SOFTWARE\WOW6421Node\PHP\x.y] and [HKEY_LOCAL_MACHINE\SOFTWARE\WOW6421Node\PHP\x] , where x, y and z mean the PHP major, minor and release versions. If there is a value for IniFilePath in any of these keys, the first one found will be used as the location of the php.ini (Windows only).
[HKEY_LOCAL_MACHINE\SOFTWARE\PHP] or [HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\PHP] , value of IniFilePath (Windows only).
Current working directory (except CLI).
The web server’s directory (for SAPI modules), or directory of PHP (otherwise in Windows).
Windows directory ( C:\windows or C:\winnt ) (for Windows), or —with-config-file-path compile time option.

If php-SAPI.ini exists (where SAPI is the SAPI in use, so, for example, php-cli.ini or php-apache.ini ), it is used instead of php.ini . The SAPI name can be determined with php_sapi_name() .

Note:

The Apache web server changes the directory to root at startup, causing PHP to attempt to read php.ini from the root filesystem if it exists.

Using environment variables can be used in php.ini as shown below.

Example #1 php.ini Environment Variables

; PHP_MEMORY_LIMIT is taken from environment memory_limit = $

The php.ini directives handled by extensions are documented on the respective pages of the extensions themselves. A list of the core directives is available in the appendix. Not all PHP directives are necessarily documented in this manual: for a complete list of directives available in your PHP version, please read your well commented php.ini file. Alternatively, you may find » the latest php.ini from Git helpful too.

Example #2 php.ini example

; any text on a line after an unquoted semicolon (;) is ignored [php] ; section markers (text within square brackets) are also ignored ; Boolean values can be set to either: ; true, on, yes ; or false, off, no, none register_globals = off track_errors = yes ; you can enclose strings in double-quotes include_path = ".:/usr/local/lib/php" ; backslashes are treated the same as any other character include_path = ".;c:\php\lib"

It is possible to refer to existing .ini variables from within .ini files. Example: open_basedir = $ «:/new/dir» .

Scan directories

It is possible to configure PHP to scan for .ini files in a directory after reading php.ini . This can be done at compile time by setting the —with-config-file-scan-dir option. The scan directory can then be overridden at run time by setting the PHP_INI_SCAN_DIR environment variable.

It is possible to scan multiple directories by separating them with the platform-specific path separator ( ; on Windows, NetWare and RISC OS; : on all other platforms; the value PHP is using is available as the PATH_SEPARATOR constant). If a blank directory is given in PHP_INI_SCAN_DIR , PHP will also scan the directory given at compile time via —with-config-file-scan-dir.

Within each directory, PHP will scan all files ending in .ini in alphabetical order. A list of the files that were loaded, and in what order, is available by calling php_ini_scanned_files() , or by running PHP with the —ini option.

Assuming PHP is configured with --with-config-file-scan-dir=/etc/php.d, and that the path separator is . $ php PHP will load all files in /etc/php.d/*.ini as configuration files. $ PHP_INI_SCAN_DIR=/usr/local/etc/php.d php PHP will load all files in /usr/local/etc/php.d/*.ini as configuration files. $ PHP_INI_SCAN_DIR=:/usr/local/etc/php.d php PHP will load all files in /etc/php.d/*.ini, then /usr/local/etc/php.d/*.ini as configuration files. $ PHP_INI_SCAN_DIR=/usr/local/etc/php.d: php PHP will load all files in /usr/local/etc/php.d/*.ini, then /etc/php.d/*.ini as configuration files.

Find the correct php.ini file

I am currently trying to locate the correct php.ini file to edit it and restart apache so the changes will take place and I’m stumped. I have found three different php.ini files (no idea why there are three) this is how I found the files

$ sudo find / -name php.ini /etc/php5/cli/php.ini /etc/php5/apache2/php.ini /etc/php5/cgi/php.ini

$ sudo php -i | grep 'Configuration File' Configuration File (php.ini) Path => /etc/php5/cli Loaded Configuration File => /etc/php5/cli/php.ini

sudo service apache2 restart

* Restarting web server apache2

echo ini_get('post_max_size');

Which was supposed to be changed to 20M but was still only 2M I tried rebooting my computer thinking maybe that would stop the apache server and reload the php.ini file with the correct setting, but alas that attempt also failed. Is there any chance there could be another php.ini file that could be interfering?

@Michael The file is /etc/php/5.6/apache2/php.ini in Ubuntu 16.04 LTS Xenial Xerus, where 5.6/ is the version of php installed. First copy the file to php.original.ini then open for editing with sudo gedit /etc/php/5.6/apache2/php.ini

The three files you have there are each meant for different uses.

/etc/php/5.6/cli/php.ini is for the CLI PHP program, which you found by running php on the terminal.

/etc/php/5.6/cgi/php.ini is for the php-cgi system which isn’t specifically used in this setup.

/etc/php/5.6/apache2/php.ini is for the PHP plugin used by Apache. This is the one you need to edit for changes to be applied for your Apache setup which utilizes the in-built PHP module to Apache.

/etc/php/5.6/fpm/php.ini is for the php5-fpm processor, which is a fastcgi-compatible ‘wrapper’ for PHP processing (such as to hand off from NGINX to php5-fpm ) and runs as a standalone process on the system (unlike the Apache PHP plugin)

For versions of Ubuntu lower than 16.04, /etc/php/5.6/ , /etc/php/7.0/ , /etc/php/7.1/ , and so on, are replaced by /etc/php5/ and so on. Otherwise, these paths remain accurate. Adapt this accordingly for your environment, replacing the 5.6 or number with the actual version folder that exists on your environment.
