PHP configuration can be made in a number of different places:
Some configuration settings can only be set in certain places and there's certain Apache and PHP settings that would prevent you from doing any PHP config changes in .htaccess or with your PHP script. But assuming that a given PHP setting can be set in all of the above places, in what order is this configuration read? In other words what overrides what? (I'm assuming that ini_set() overrides any of the previous settings).

The PHP configuration file allows you to configure the modules enabled, the email settings or the size of the upload files. It is located at installdir/php/etc/php. ini. For example, to modify the default upload limit for PHP, update the PHP configuration file following these instructions.
Check php. ini in CLI (Command Line Interface): To know about php. ini, simply run on CLI. It look for Loaded Configuration File in output for the location of php.
The php. ini file is the default configuration file for running applications that require PHP. It is used to control variables such as upload sizes, file timeouts, and resource limits. php. ini file is the configuration file.
PHP directives are the configuration settings used to control various behaviours of PHP functions on your site. This can include for example; the memory limit assigned for PHP, the maximum amount of time before a PHP process will time out and the maximum file-size that could be uploaded via a PHP script.
There's compile-time settings before php.ini. The rest of the stages aren't really "configuration". They're more of a way to override settings established in a previous stage. PHP will quite happily run without any other config directives in php.ini/http.conf/.htaccess. php.ini does list (almost?) all the configuration settings available, but that's just a courtesy so you don't have to dig around in the docs to find the one setting you do want to override.
