note 114574 added to function.array-walk-recursive

array_walk_recursive itself cannot unset values. Even though you can pass array by reference, unsetting the value in the callback will only unset the variable in that scope. <?php /** * http://uk1.php.net/array_walk_recursive implementation that is used to remove nodes from the array. * * @param array The input array. * @param callable $callback Function must return boolean value indicating whether to remove the node. * @return array */ function walk_recursive_remove (array $array, callable $callback) { foreach ($array as $k => $v) { if (is_array($v)) { $v = walk_recursive_remove($v, $callback); } else { if ($callback($v, $k)) { unset($array[$k]); } } } return $array; } ?> An up to date implementation of the above function can be looked up from https://github.com/gajus/marray/blob/master/src/marray.php#L116. ---- Server IP: 87.117.229.81 Probable Submitter: 46.28.49.140 ---- Manual Page -- http://php.net/manual/en/function.array-walk-recursive.php Edit -- https://master.php.net/note/edit/114574 Del: integrated -- https://master.php.net/note/delete/114574/integrated Del: useless -- https://master.php.net/note/delete/114574/useless Del: bad code -- https://master.php.net/note/delete/114574/bad+code Del: spam -- https://master.php.net/note/delete/114574/spam Del: non-english -- https://master.php.net/note/delete/114574/non-english Del: in docs -- https://master.php.net/note/delete/114574/in+docs Del: other reasons-- https://master.php.net/note/delete/114574 Reject -- https://master.php.net/note/reject/114574 Search -- https://master.php.net/manage/user-notes.php
