note 110590 added to function.array-intersect

If you're looking for a relatively easy way to strictly intersect keys and values recursively without array key reordering, here's a simple recursive function: function array_intersect_recursive($array1, $array2) { foreach($array1 as $key => $value) { if (!isset($array2[$key])) { unset($array1[$key]); } else { if (is_array($array1[$key])) { $array1[$key] = array_intersect_recursive($array1[$key], $array2[$key]); } elseif ($array2[$key] !== $value) { unset($array1[$key]); } } } return $array1; } ---- Server IP: 64.68.200.35 Probable Submitter: 184.69.29.10 ---- Manual Page -- http://www.php.net/manual/en/function.array-intersect.php Edit -- https://master.php.net/note/edit/110590 Del: integrated -- https://master.php.net/note/delete/110590/integrated Del: useless -- https://master.php.net/note/delete/110590/useless Del: bad code -- https://master.php.net/note/delete/110590/bad+code Del: spam -- https://master.php.net/note/delete/110590/spam Del: non-english -- https://master.php.net/note/delete/110590/non-english Del: in docs -- https://master.php.net/note/delete/110590/in+docs Del: other reasons-- https://master.php.net/note/delete/110590 Reject -- https://master.php.net/note/reject/110590 Search -- https://master.php.net/manage/user-notes.php
