Description
___________
 
The ``php.ini`` directive ``assert.callback`` is deprecated, alongside several features from the assert functions. It should not be set anymore in the code.

Note that a call to ``ini_get()`` will not generate the warning: only the ``ini_set()``.

Example
_______

.. code-block:: php

   <?php
   
   ini_set('assert.callback', 1);
   
   ?>

Solutions
_________

+ Remove the call to ``assert.callback`` and its dependencies.
