Hi, i tested it with php 5.1.3-dev snap and it works correctly for me. btw. $return = $notdefined_variable; is a bad style for coding and this happens in your situation in a undefined behavior. If you think this is a bug please go to http://bugs.php.net and report them there. 2006/2/4, Bogdan Ribic <ribicb@xxxxxxxxx>: > > Hi all, > > I've found a strange bug with extract($GLOBALS, EXTR_REFS), and it > only shows up if you try to access a non-existent variable or array > member before that.
