#28325 [NEW]: serialization of objects

From: antonr at game dot permonline dot ru Operating system: Win32 PHP version: 5CVS-2004-05-08 (dev) PHP Bug Type: Class/Object related Bug description: serialization of objects Description: ------------ I have one object with property "myclass1", referenced to second object. And property "myclass2" of second object, referenced to first object. When I serialize the first object and unserialize the result string, I get three objects: two copies of first object and a copy of second object. Reproduce code: --------------- <?php class MyClass1 { public $myclass2; public $number; } class MyClass2 { public $myclass1; } $a = new MyClass1; $a->number = 1; $a->myclass2 = new MyClass2; $a->myclass2->myclass1 = $a; $b = unserialize(serialize($a)); $b->number = 2; echo $b->number; echo "\n"; echo $b->myclass2->myclass1->number; ?> Expected result: ---------------- If serialization was made correctly, then we would get that $b and $b->myclass2->myclass1 are references to one instance, and the output of script must be: 2 2 Actual result: -------------- The actual output is 2 1 this means, that $b and $b->myclass2->myclass1 aren't references to the same instance -- Edit bug report at http://bugs.php.net/?id=28325&edit=1 -- Try a CVS snapshot (php4): http://bugs.php.net/fix.php?id=28325&r=trysnapshot4 Try a CVS snapshot (php5): http://bugs.php.net/fix.php?id=28325&r=trysnapshot5 Fixed in CVS: http://bugs.php.net/fix.php?id=28325&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=28325&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=28325&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=28325&r=needscript Try newer version: http://bugs.php.net/fix.php?id=28325&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=28325&r=support Expected behavior: http://bugs.php.net/fix.php?id=28325&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=28325&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=28325&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=28325&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=28325&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=28325&r=dst IIS Stability: http://bugs.php.net/fix.php?id=28325&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=28325&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=28325&r=float
