note 97210 deleted from function.array-intersect by cmb

Note Submitter: james -at- bandit.co -dot- nz ---- I needed an array_intersect that would delete the intersecting values from the original array. Voila: <?php // array_intersect that splits the needle array into two - one filled with "intersected" results, and one filled with the remainder function array_intersect_split(&$needle, $haystack, $preserve_keys = false) { if(!is_array($needle) || !is_array($haystack)) return false; $new_arr = array(); foreach($needle as $key => $value) { if(($loc = array_search($value, $haystack))!==false) { if(!$preserve_keys) $new_arr[] = $value; else $new_arr[$key] = $value; unset($needle[$key]); } } return $new_arr; } ?>
