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-ini'

   drwxr-xr-x  2 cytopia cytopia 4096 Mar  5 21:53 php-ini-5.2/
   drwxr-xr-x  2 cytopia cytopia 4096 Mar  5 21:53 php-ini-5.3/
   drwxr-xr-x  2 cytopia cytopia 4096 Mar  5 21:53 php-ini-5.4/
   drwxr-xr-x  2 cytopia cytopia 4096 Mar  5 21:53 php-ini-5.5/
   drwxr-xr-x  2 cytopia cytopia 4096 Apr  3 22:04 php-ini-5.6/
   drwxr-xr-x  2 cytopia cytopia 4096 Mar  5 21:53 php-ini-7.0/
   drwxr-xr-x  2 cytopia cytopia 4096 Mar  5 21:53 php-ini-7.1/
   drwxr-xr-x  2 cytopia cytopia 4096 Mar  5 21:53 php-ini-7.2/
   drwxr-xr-x  2 cytopia cytopia 4096 Mar  5 21:53 php-ini-7.3/
   drwxr-xr-x  2 cytopia cytopia 4096 Mar  5 21:53 php-ini-7.4/

Customization is achieved by placing a file into ``cfg/php-ini-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 contains two example files:
``devilbox-php.ini-default`` and ``devilbox-php.ini-xdebug``.

**devilbox-php.ini-default**

This file holds the exact settings that are currently in place by each PHP-FPM container.
Copy it (do not simply rename it) to a different file ending by ``.ini`` and start adjusting it.

**devilbox-php.ini-xdebug**

This file holds some sane example configuration to get you started with Xdebug.
Copy it (do not simply rename it) to a different file ending by ``.ini`` and start adjusting it.

.. important:: For Xdebug to work, there are other changes requires as well: :ref:`configure_php_xdebug`

**How to apply the settings**

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