From: hawcue at yahoo dot com Operating system: Windows XP PHP version: 4.3.4 PHP Bug Type: Class/Object related Bug description: inconsistency of unserializing references Description: ------------ Please read the codes first. The actual output shows two copies of $parentNode are generated by unserialize(). However, this is not what I expect because I am using reference and $newParent->child->parent and $newParent should refer to the same storage if serialize/unserialize works correctly. The problem can be partially solved by using the following line to do serialize: $str = serialize(&$parentNode); // an ampersand is used This will generate a compiling warning (depreciation of using ampersand in function parameters). Reproduce code: --------------- class Node { var $value; var $child; var $parent; function Node($value) { $this->value = $value; } function setParent(&$parent) { $this->parent = &$parent; } function setChild(&$child) { $this->child = &$child; } } $parentNode = new Node('parent'); $childNode = new Node('child'); $parentNode->setChild($childNode); $childNode->setParent($parentNode); $str = serialize($parentNode); $newParent = unserialize($str); $newParent->value = 'new parent'; echo $newParent->child->parent->value; echo $newParent->value; Expected result: ---------------- new parent new parent Actual result: -------------- parent new parent -- Edit bug report at http://bugs.php.net/?id=27336&edit=1 -- Try a CVS snapshot (php4): http://bugs.php.net/fix.php?id=27336&r=trysnapshot4 Try a CVS snapshot (php5): http://bugs.php.net/fix.php?id=27336&r=trysnapshot5 Fixed in CVS: http://bugs.php.net/fix.php?id=27336&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=27336&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=27336&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=27336&r=needscript Try newer version: http://bugs.php.net/fix.php?id=27336&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=27336&r=support Expected behavior: http://bugs.php.net/fix.php?id=27336&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=27336&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=27336&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=27336&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=27336&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=27336&r=dst IIS Stability: http://bugs.php.net/fix.php?id=27336&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=27336&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=27336&r=float
