That seems like a change in behavior just to change it. Continuing on the off-topic notes.. I would rather go with an alternative implementation based upon interfaces (i.e. dirwrapper, filesystemwrapper, streamwrapper...) and spec it out before adding random magical things that took over 7 years for people to figure out and document. And lets not mention the stream_filter_register() and stream_bucket_new() voodoo. -Hannes -- PHP Internals - PHP Runtime Development Mailing List To unsubscribe, visit: http://www.php.net/unsub.php
