Don’t Copy Extra Variables in PHP

Some people like to try and make their code more appealing by copying predefined variables to smaller-named variables. This is redundant and could potentially double the memory of your script.

Google Code has bad and good examples of variable usage:

Good:

echo strip_tags($_POST['name']);


Bad :

$name = strip_tags($_POST['name']);
echo $name;
