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 This result is expected. In "a" == 0, "a" is converted to int. For strict comparison, use the third parameter. http://docs.php.net/in-array Previous Comments: ------------------------------------------------------------------------ [2008-02-22 12:24:14] markus dot kalkbrenner at arcor dot de Description: ------------ in_array() returns true if needle exists as key with int(0) as value, but should return false because needle doesn't exist as value.
