note 43568 added to function.array-intersect

I couldn't find any array union functionality in PHP (extracting the common elements between two arrays), so the best method I could think of was to intersect them from both directions: $arr1 = array(1,2,3,4); $arr2 = array(2,4,6,8); $union = array_intersect($arr2, array_intersect($arr1, $arr2)); print_r($union); output: Array ( [0] => 2 [1] => 4 ) This result is the union of the two arrays. ---- Manual Page -- http://www.php.net/manual/en/function.array-intersect.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+43568 Delete -- http://master.php.net/manage/user-notes.php?action=delete+43568&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+43568&report=yes Search -- http://master.php.net/manage/user-notes.php
