note 106519 added to class.recursivearrayiterator

If you are iterating over a multi-dimensional array of objects, you may be tempted to use a RecursiveArrayIterator within a RecursiveIteratorIterator. You are likely to get baffling results if you do. That is because RecursiveArrayIterator treats all objects as having children, and tries to recurse into them. But if you are interested in having your RecursiveIteratorIterator return the objects in your multi-dimensional array, then you don't want the default setting LEAVES_ONLY, because no object can be a leaf (= has no children). The solution is to extend the RecursiveArrayIterator class and override the hasChildren method appropriately. Something like the following might be suitable: <?php class RecursiveArrayOnlyIterator extends RecursiveArrayIterator { public function hasChildren() { return is_array($this->current()); } } ?> Of course, this simple example will not recurse into ArrayObjects either! ---- Server IP: 69.147.83.197 Probable Submitter: 109.151.9.102 ---- Manual Page -- http://www.php.net/manual/en/class.recursivearrayiterator.php Edit -- https://master.php.net/note/edit/106519 Del: integrated -- https://master.php.net/note/delete/106519/integrated Del: useless -- https://master.php.net/note/delete/106519/useless Del: bad code -- https://master.php.net/note/delete/106519/bad+code Del: spam -- https://master.php.net/note/delete/106519/spam Del: non-english -- https://master.php.net/note/delete/106519/non-english Del: in docs -- https://master.php.net/note/delete/106519/in+docs Del: other reasons-- https://master.php.net/note/delete/106519 Reject -- https://master.php.net/note/reject/106519 Search -- https://master.php.net/manage/user-notes.php
