Hello Jim, Aziz and thanks for your answer :) So the `glob` function is “just” a linux’s glob porting with all it’s features and the Iterator is a more strict (regarding to RFCs) implementation of the `glob` feature… We made some benches and did not spot a huge difference between an Iterator combination and a simple `glob` call. The specific `glob` features are activated by some flags so I think it’s not a big problem to does not have them when using only the `GlobIterator`.

The difference comes naturally with any improvements on any language. newer functionality doesn't always match the old, specially when the old are still usable side by side. > -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
