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);

?>
