note 108609 added to class.iterator

If you have a custom iterator that may throw an exception in it's current() method, there is no way to catch the exception without breaking a foreach loop. The following for loop allows you to skip elements for which $iterator->current() throws an exception, rather than breaking the loop. <?php for ($iterator->rewind(); $iterator->valid(); $iterator->next()) { try { $value = $iterator->current(); } catch (Exception $exception) { continue; } # ... } ?> ---- Server IP: 94.76.225.145 Probable Submitter: 86.140.183.231 ---- Manual Page -- http://www.php.net/manual/en/class.iterator.php Edit -- https://master.php.net/note/edit/108609 Del: integrated -- https://master.php.net/note/delete/108609/integrated Del: useless -- https://master.php.net/note/delete/108609/useless Del: bad code -- https://master.php.net/note/delete/108609/bad+code Del: spam -- https://master.php.net/note/delete/108609/spam Del: non-english -- https://master.php.net/note/delete/108609/non-english Del: in docs -- https://master.php.net/note/delete/108609/in+docs Del: other reasons-- https://master.php.net/note/delete/108609 Reject -- https://master.php.net/note/reject/108609 Search -- https://master.php.net/manage/user-notes.php
