Function Called With Other Case Than Defined
++++++++++++++++++++++++++++++++++++++++++++

  Functions and methods are defined with a specific case. Often, this is done on purpose,
either to distinguish the method from others, such as PHP natives functions, or to follow a naming
convention. 

PHP functions are case insensitive, which leads to situations like : 
It is recommended to use the same casing in the function call and the function definition.

.. code-block:: php
   
   <?php
     function myUtility($arg) { 
       /* some code here */
     } 
   
      myutility($var);
   ?>
