From: denis at bytezone dot com
Operating system: windows vista
PHP version: 5.2.0
PHP Bug Type: Unknown/Other Function
Bug description: Nesting/recursion runtime error
Description:
------------
When I create objects which contain a nested pointer back to itself, it
cannot be compared with another object for equality.
Error only occurs when the two objects being compared are the same
object.
Also, using === for comparison works correctly.
Reproduce code:
---------------
<?php
$thing = new Thing ();
$otherThing = new OtherThing ();
$thing->otherThing = $otherThing;
$otherThing->thing = $thing;
$thing2 = $thing;
if ($thing == $thing2)
print "equal";
else
print "not equal";
Class Thing
{
public $otherThing;
}
Class OtherThing
{
public $thing;
}
?>
Expected result:
----------------
I expect it to print 'equal'
Actual result:
--------------
Fatal error: Nesting level too deep - recursive dependency? in
