Is someone can explain me this..:
$bob = $_POST['foo'] ;
is_int($bob) FAIL but is_numeric($bob) is OK .
So i know i cannot use is_int directly on $_POST but here i transfert the post value in another variable before..
Whats wrong please ?!
Test is_int doen't work after passing $_POST var in simple $var
