note 86695 deleted from function.in-array by cmb

Note Submitter: james dot ellis at gmail dot com ---- Be aware of oddities when dealing with 0 (zero) values in an array... This script: <?php $array = array('testing',0,'name'); var_dump($array); //this will return true var_dump(in_array('foo', $array)); //this will return false var_dump(in_array('foo', $array, TRUE)); ?> It seems in non strict mode, the 0 value in the array is evaluating to boolean FALSE and in_array returns TRUE. Use strict mode to work around this peculiarity. This only seems to occur when there is an integer 0 in the array. A string '0' will return FALSE for the first test above (at least in 5.2.6).
