note 39456 added to function.aggregate

In which version exactly was the function aggregate() added to php? Can it be disabled? I got an error from a user running php 4.2.2, but the errors shows up after a check with function_exists() referred to aggregate()... Does then user need to pdate php or it is part of an extension to enable? Please hurry up! :| ---- Manual Page -- http://www.php.net/manual/en/function.aggregate.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+39456 Delete -- http://master.php.net/manage/user-notes.php?action=delete+39456&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+39456&report=yes Search -- http://master.php.net/manage/user-notes.php
