Since PHP 5.3.0, PHP includes support for configuration INI files on a per-directory basis. These files are processed only by the CGI/FastCGI SAPI. This functionality obsoletes the PECL htscanner extension. If you are using Apache, use .htaccess files for the same effect.
In addition to the main php.ini file, PHP scans for INI files in each directory, starting with the directory of the requested PHP file, and working its way up to the current document root (as set in $_SERVER['DOCUMENT_ROOT']). In case the PHP file is outside the document root, only its directory is scanned.
Only INI settings with the
modes PHP_INI_PERDIR and
PHP_INI_USER will be recognized in .user.ini-style INI
files.
Two new INI directives, user_ini.filename and user_ini.cache_ttl control the use of user INI files.
user_ini.filename sets the name of the file PHP looks for in each directory; if set to an empty string, PHP doesn't scan at all. The default is .user.ini.
user_ini.cache_ttl controls how often user INI files are re-read. The default is 300 seconds (5 minutes).
If you have no idea what "PHP_INI_PERDIR" or "PHP_INI_USER" are or how they relate to setting a .user.ini file, take a look at the ini.list page: http://www.php.net/manual/en/ini.list.php
Basically, anything in the "Changeable" column labeled as PHP_INI_SYSTEM can't be set in the .user.ini file (so quit trying). It can ONLY be set at the main php.ini level.
"If you are using Apache, use .htaccess files for the same effect."
To clarify, this applies only to Apache module mode. If you put php directives in .htaccess on an Apache CGI/FastCGI server, this will bomb the server out with a 500 error. Thus, you unfortunately cannot create a config which caters for both types of hosting, at least not in any straightforward way.
This article should be made clearer.
".htaccess-style INI files" meant to me that the ini settings had to follow the syntax used in .htaccess, but this is not the case!
You have to use
register_globals=on
and not
php_flag register_globals on
Also, the changes can take a while to propagate to all processes if you have a long process time out.
Restarting php-fpm can give you an answer quicker :)
One of the most used is to limit the uploading size and memory limit:
upload_max_filesize = 1000M
post_max_size=1005M
max_execution_time=120
