note 106943 added to class.parentiterator

ParentIterator is just a RecursiveFilterIterator whos accept() method calls the RecursiveFilterIterator->hasChildren() method to filter itself. Basically, it filters out leaf nodes. For example This would yield all files and directories <?php $rdi = new RecursiveDirectoryIterator(__DIR__); $iter = new RecursiveIteratorIterator($rdi, RecursiveIteratorIterator::CHILD_FIRST); ?> wrapping that in a ParentIterator would filter it down to just directories <?php $rdi = new RecursiveDirectoryIterator(__DIR__); $iter = new RecursiveIteratorIterator($rdi, RecursiveIteratorIterator::CHILD_FIRST); $dirsOnly = new ParentIterator($iter); ?> ---- Server IP: 69.147.83.197 Probable Submitter: 76.14.54.90 ---- Manual Page -- http://www.php.net/manual/en/class.parentiterator.php Edit -- https://master.php.net/note/edit/106943 Del: integrated -- https://master.php.net/note/delete/106943/integrated Del: useless -- https://master.php.net/note/delete/106943/useless Del: bad code -- https://master.php.net/note/delete/106943/bad+code Del: spam -- https://master.php.net/note/delete/106943/spam Del: non-english -- https://master.php.net/note/delete/106943/non-english Del: in docs -- https://master.php.net/note/delete/106943/in+docs Del: other reasons-- https://master.php.net/note/delete/106943 Reject -- https://master.php.net/note/reject/106943 Search -- https://master.php.net/manage/user-notes.php
