strange behaviour of in_array:

If you have an array like:
<?php
$a = array(0,1,2,3,4,5);
in_array("bla", $a) returns true
in_array("bla6", $a) returns true
in_array("6bla", $a) returns false
?>

If you have an array like (without 0):
<?php
$a = array(1,2,3,4,5);
in_array("bla", $a) returns false
in_array("6bla", $a) returns false
in_array("5bla", $a) returns true
?>

so better use strict arg!
