#30791 [NEW]: overload and serialize produce unexpected behaviour

From: alan at akbkhome dot com Operating system: na PHP version: 5CVS-2004-11-15 (dev) PHP Bug Type: Zend Engine 2 problem Bug description: overload and serialize produce unexpected behaviour Description: ------------ If an object is overloaded (with __call()), then serializ'ing the object will fail unless __sleep() is defined. It would be far clearer to either a) - force __sleep to defined on overloaded objects (E_WARN?) b) - dont call __call() with the __sleep() request. Reproduce code: --------------- class a { public $a = 4; function __call($a,$b) { return "unknown method"; } } $b = new a; echo serialize($b); Expected result: ---------------- Warning: __sleep is not defined on an overloaded object with __call() Actual result: -------------- Warning about unexpected return value to __sleep() and an empty string output from serialize() -- Edit bug report at http://bugs.php.net/?id=30791&edit=1 -- Try a CVS snapshot (php4): http://bugs.php.net/fix.php?id=30791&r=trysnapshot4 Try a CVS snapshot (php5.0): http://bugs.php.net/fix.php?id=30791&r=trysnapshot50 Try a CVS snapshot (php5.1): http://bugs.php.net/fix.php?id=30791&r=trysnapshot51 Fixed in CVS: http://bugs.php.net/fix.php?id=30791&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=30791&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=30791&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=30791&r=needscript Try newer version: http://bugs.php.net/fix.php?id=30791&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=30791&r=support Expected behavior: http://bugs.php.net/fix.php?id=30791&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=30791&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=30791&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=30791&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=30791&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=30791&r=dst IIS Stability: http://bugs.php.net/fix.php?id=30791&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=30791&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=30791&r=float MySQL Configuration Error: http://bugs.php.net/fix.php?id=30791&r=mysqlcfg
