#31449 [Asn->Bgs]: Comparison of class with recursive references causes fatal

ID: 31449 Updated by: stas@php.net Reported By: marcus at lastcraft dot com -Status: Assigned +Status: Bogus Bug Type: Class/Object related Operating System: * PHP Version: 5CVS-2005-03-06 Assigned To: andi New Comment: Thank you for taking the time to write to us, but this is not a bug. Please double-check the documentation available at http://www.php.net/manual/ and the instructions on how to report a bug at http://bugs.php.net/how-to-report.php I don't think it's a bug. You can not compare these objects since they contain circular references, so comparison process descends to the endless loop. You may want to use custom method to compare objects - bit-comparison of objects is generally not the best idea.

The script below causes a fatal error. This is just the simplest example I could find of a whole class of these problems. Makes comparing any object problematical. yours, Marcus Reproduce code: --------------- <?php class Recursive { private $me; function __construct() { $this->me = $this; } } new Recursive() != new Recursive(); ?> Expected result: ---------------- Nothing as the comparison is not output. Actual result: -------------- Fatal error with nesting too deep. ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=31449&edit=1
