General
=======

You can set custom php.ini configuration options for each PHP version separately.
See the directory structure for PHP configuration directories inside ``./cfg/`` directory:

.. code-block:: bash

    host> ls -l path/to/devilbox/cfg/ | grep 'php'

    drwxr-xr-x  2 cytopia cytopia 4096 Mar  5 21:53 php-fpm-5.4/
    drwxr-xr-x  2 cytopia cytopia 4096 Mar  5 21:53 php-fpm-5.5/
    drwxr-xr-x  2 cytopia cytopia 4096 Apr  3 22:04 php-fpm-5.6/
    drwxr-xr-x  2 cytopia cytopia 4096 Mar  5 21:53 php-fpm-7.0/
    drwxr-xr-x  2 cytopia cytopia 4096 Mar  5 21:53 php-fpm-7.1/
    drwxr-xr-x  2 cytopia cytopia 4096 Mar  5 21:53 php-fpm-7.2/

Customization is achieved by placing a file into ``cfg/php-fpm-X.X/`` (where ``X.X`` stands for
your PHP version).  The file must end by ``.ini`` in order to be sourced by the PHP-FPM server.

Each of the PHP ini configuration directories already contain an example file:
``devilbox-custom.ini-example``, that can simply be renamed to ``devilbox-custom.ini``.
This file holds same example values that can be adjusted or commented out.

In order for the changes to be applied, you will have to restart the Devilbox.
