#45653 [NEW]: ArrayObject does not call offsetSet when an element is incremented

From: agalkin at agalkin dot ru Operating system: Mac OS X 10.5.4 PHP version: 5.2.6 PHP Bug Type: SPL related Bug description: ArrayObject does not call offsetSet when an element is incremented Description: ------------ When an element of ArrayObject is incremented (++ operation), the object does not call its offsetSet method. I've tried overloading all public methods in ArrayObject: offsetGet is called, but not offsetSet or any other. Same with decrementing (--). This behaviour makes it impossible to handle all array modifications by overloading ArrayObject methods in derived class. Reproduce code: --------------- class myArray extends ArrayIterator { public function offsetSet($index, $newval) { echo "offsetSet called\n"; return parent::offsetSet($index, $newval); } } $a = new myArray(array('x' => 1)); echo "x += 1\n"; $a['x'] += 1; // calls offsetGet, then offsetSet with updated value echo $a['x']."\n"; echo "x++\n"; $a['x']++; // only calls offsetGet echo $a['x']."\n"; // but the value gets incremented Expected result: ---------------- x += 1 offsetSet called 2 x++ offsetSet called 3 Actual result: -------------- x += 1 offsetSet called 2 x++ 3 -- Edit bug report at http://bugs.php.net/?id=45653&edit=1 -- Try a CVS snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=45653&r=trysnapshot52 Try a CVS snapshot (PHP 5.3): http://bugs.php.net/fix.php?id=45653&r=trysnapshot53 Try a CVS snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=45653&r=trysnapshot60 Fixed in CVS: http://bugs.php.net/fix.php?id=45653&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=45653&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=45653&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=45653&r=needscript Try newer version: http://bugs.php.net/fix.php?id=45653&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=45653&r=support Expected behavior: http://bugs.php.net/fix.php?id=45653&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=45653&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=45653&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=45653&r=globals PHP 4 support discontinued: http://bugs.php.net/fix.php?id=45653&r=php4 Daylight Savings: http://bugs.php.net/fix.php?id=45653&r=dst IIS Stability: http://bugs.php.net/fix.php?id=45653&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=45653&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=45653&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=45653&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=45653&r=mysqlcfg
