Overwriting Variable
++++++++++++++++++++

  Replacing the content of a variable by something different is prone to errors. For example, it is not obvious if the $text variable is plain text or HTML text. 
Besides, it is possible that the source is needed later, for extra processing. 

Note that accumulators, like += .=  or [] etc., that are meant to collect lots of values with consistent type are OK.

.. code-block:: php
   
   <?php
   
   // Confusing
   $text = htmlentities($text);
   
   // Better
   $textHTML = htmlentities($text);
   
   ?>
