I was using this solution within a function that returns a default if the array index is not defined. It worked quite nicely until I tried to apply it to $GLOBALS and I got the Nesting level too deep. So I'm looking for another, highly efficient, solution that won't issue php notices for undefined indexes. Test script: <?php $GLOBALS == $GLOBALS; Expected result: Actual result: Fatal error: Nesting level too deep - recursive dependency? ------------------------------------------------------------------------ [2011-07-02 00:36:43] trefighter2334 at aol dot com Any word on this? I'm also experiencing this bug in both Ubuntu (Zend Server AND vanilla PHP) and Windows 7 (Zend Server). I guess I'm off to go find some hackish way to detect array recursion. ------------------------------------------------------------------------ [2010-04-11 19:38:45] neel dot basu dot z at gmail dot com **If It is not a Bug then Recursive Reference Detection is IMPOSSIBLE in PHP. cause spl_object_hash() doesn't work on array or scaler types. ------------------------------------------------------------------------ [2010-04-11 19:35:59] neel dot basu dot z at gmail dot com Description: ------------ When there is recursive reference in an array comparison yields Fatal Error.
