note 54429 added to function.array-intersect-key

I tried to use this function with PHP 5.0.4 under windows but the function does not seem to be implemented. (Fatal error: Call to undefined function array_intersect_key()) This works as a workaround for 2 arrays at least: function array_intersect_key($arr1, $arr2) { $res = array(); foreach($arr1 as $key=>$value) { if(array_key_exists($key, $arr2)) $res[$key] = $arr1[$key]; } return $res; } ---- Manual Page -- http://www.php.net/manual/en/function.array-intersect-key.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+54429 Delete: added to the manual -- http://master.php.net/manage/user-notes.php?action=delete+54429&report=yes&reason=added+to+the+manual Delete: bad code -- http://master.php.net/manage/user-notes.php?action=delete+54429&report=yes&reason=bad+code Delete: spam -- http://master.php.net/manage/user-notes.php?action=delete+54429&report=yes&reason=spam Delete: useless -- http://master.php.net/manage/user-notes.php?action=delete+54429&report=yes&reason=useless Delete: non-english -- http://master.php.net/manage/user-notes.php?action=delete+54429&report=yes&reason=non-english Delete: other reasons -- http://master.php.net/manage/user-notes.php?action=delete+54429&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+54429&report=yes Search -- http://master.php.net/manage/user-notes.php
