Right now ther is no place in SPL that would benefit. But both SXE and PDO have to create empty instances to allow code that does not need further cehecks before sending to foreach(). So the idea is actually some speed improvement and in case of SimpleXML i'd like to be able to check existance of a sub element by the following: !is_null($sxe->element) Best regards, Marcus -- PHP Internals - PHP Runtime Development Mailing List To unsubscribe, visit: http://www.php.net/unsub.php
