Previous Comments: ------------------------------------------------------------------------ [2020-03-24 08:53:49] 6562680 at gmail dot com Description: ------------ Am using array_walk/*_recursive to work with reports (seems like): ``` [ 'created' => [], 'updated' => [], // * => [] ] ``` When we have large amount of records we should run 10000 callbacks even if statement ``` static $break = false; if ($break) return null; $break = true; ``` was declared The solution could be ``` class BreakException extends \Exception {} try { array_walk_recursive($array, function () { throw new BreakException(); }); } catch (Exception $e) { } ``` Would be great to implement some statement like foreach break to avoid building stack trace while using that feature (because of foreach supports only single level traversing) Thank you.
