Summary: [recursive reference In Array] Nesting level too
deep
Status: Open
Type: Bug
Package: Scripting Engine problem
Operating System: Linux
PHP Version: 5.3.2
Block user comment: N
Private report: N
New Comment:
There is a comment in http://us.php.net/manual/en/function.is-array.php#98156
which suggests using casting to array to check if an array is actually an
array. 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?

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.
