note 102681 added to function.in-array

strange behaviour of in_array:

If you have an array like:
$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):
$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!
