Please double-check the documentation available at http://www.php.net/manual/ and the instructions on how to report a bug at http://bugs.php.net/how-to-report.php in_array() does a loose comparison by default, and 0 == 'some string not INT'. If you need a strict comparison then pass true for the third argument. http://www.php.net/in-array Previous Comments: ------------------------------------------------------------------------ [2013-09-09 07:35:53] sv3tli0 at bgspot dot eu Description: ------------ Wrong result if you are checking array for existing integer 0, when array has none integer values..
