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 D:\xampp\htdocs\scraping\test.php on line 11 -- Edit bug report at http://bugs.php.net/?id=40382&edit=1 -- Try a CVS snapshot (PHP 4.4): http://bugs.php.net/fix.php?id=40382&r=trysnapshot44 Try a CVS snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=40382&r=trysnapshot52 Try a CVS snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=40382&r=trysnapshot60 Fixed in CVS: http://bugs.php.net/fix.php?id=40382&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=40382&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=40382&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=40382&r=needscript Try newer version: http://bugs.php.net/fix.php?id=40382&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=40382&r=support Expected behavior: http://bugs.php.net/fix.php?id=40382&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=40382&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=40382&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=40382&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=40382&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=40382&r=dst IIS Stability: http://bugs.php.net/fix.php?id=40382&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=40382&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=40382&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=40382&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=40382&r=mysqlcfg
