Keys from multi dimensional array to simple array Want to traverse an multi dimensional array and get the keys back in a single dimensional array? This will do the trick: <?php public function array_walk_keys($array, $parentKey = null, &$flattened_array = null) { if(!is_array($array)) return $array; foreach( $array as $key => $val ) { $flattenedKeysArray[] = $key; if(is_array($val)) array_walk_keys($val, $key, $flattenedKeysArray); } return $flattenedKeysArray; } ---- Server IP: 72.52.91.14 Probable Submitter: 80.57.113.89 ---- Manual Page -- http://php.net/manual/en/function.array-keys.php Edit -- https://master.php.net/note/edit/118829 Del: integrated -- https://master.php.net/note/delete/118829/integrated Del: useless -- https://master.php.net/note/delete/118829/useless Del: bad code -- https://master.php.net/note/delete/118829/bad+code Del: spam -- https://master.php.net/note/delete/118829/spam Del: non-english -- https://master.php.net/note/delete/118829/non-english Del: in docs -- https://master.php.net/note/delete/118829/in+docs Del: other reasons-- https://master.php.net/note/delete/118829 Reject -- https://master.php.net/note/reject/118829 Search -- https://master.php.net/manage/user-notes.php
