∟Additional .ini Configuration Files

This section describes additional .ini files separated from the main configuration file php.ini.

What Is additional .ini File? - An additional .ini file is PHP configuration file separated from the main configuration file php.ini.

An additional .ini file is usually created during the installation process of a PHP module. It contains configuration settings specific to the installed module. For example, after installing the "mbstring" module on my Ubuntu 18 computer, I get this additional .ini file:

herong$ more /etc/php/7.2/cli/conf.d/20-mbstring.ini 

; configuration for php mbstring module
; priority=20
extension=mbstring.so

You can also create your own additional .ini file to add or update configuration settings. For example, I created the following .ini file:

herong$ sudo vi /etc/php/7.2/cli/conf.d/99-my-own.ini

memory_limit = 1024M
mysqli.default_user = herong
mysqli.default_pw = TopSecret
...

By the way, if you want to know where additional .ini files should be placed, run the "php --ini" command. Here is an example on my Ubuntu computer:

herong$ php --ini 

Configuration File (php.ini) Path: /etc/php/7.2/cli
