IHMO the documentation is not entirely clear so just to clarify: This function looks at BOTH the key and the value, so you can't use it to unset a list elements in an array if you know the keys but not the values. Instead, you can e.g. do: $a = array("foo", "bar", "baz", "quux"); $b = array(1, 3); // Elements to get rid of foreach($b as $e) unset($a[$e]); Of course this makes most sense if $b has many elements or is dynamically generated. -- http://www.php.net/manual/en/function.array-diff-assoc.php http://master.php.net/manage/user-notes.php?action=edit+31926 http://master.php.net/manage/user-notes.php?action=delete+31926 http://master.php.net/manage/user-notes.php?action=reject+31926
