From: tomas_matousek at hotmail dot com Operating system: WinXP PHP version: 5.1.1 PHP Bug Type: Scripting Engine problem Bug description: Recursive call to setter "blocks" the property
Description: ------------ In the following example, the __setter invoked by $x->a = "g1"; statement tries to write to "a" property again by $this->a = "a"; statement in the switch. This latter access is correctly considered to be recursive and thus treated as assignment to $this->a and not as a recursive call. That's ok. However, after returning from the __setter and when invoking it again by $x->b = "g2"; the $this->a = "b"; should call the __setter because we it is not a recursive call ("b" was accessed, not "a"). Hence $this->a = "b"; should invoke __setter in this case. And that doesn't happen. Reproduce code: --------------- class C { function __set($f,$v) { echo "set('$f','$v')\n"; switch ($f) { case "a": $this->a = "a"; break; case "b": $this->a = "b"; break; } } } $x = new C; $x->a = "g1"; // this blocks "a" on $x forever $x->b = "g2"; Expected result: ---------------- set('a','g1') set('b','g2') set('a','b') Actual result: -------------- set('a','g1') set('b','g2') -- Edit bug report at http://bugs.php.net/?id=35651&edit=1 -- Try a CVS snapshot (PHP 4.4): http://bugs.php.net/fix.php?id=35651&r=trysnapshot44 Try a CVS snapshot (PHP 5.1): http://bugs.php.net/fix.php?id=35651&r=trysnapshot51 Try a CVS snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=35651&r=trysnapshot60 Fixed in CVS: http://bugs.php.net/fix.php?id=35651&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=35651&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=35651&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=35651&r=needscript Try newer version: http://bugs.php.net/fix.php?id=35651&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=35651&r=support Expected behavior: http://bugs.php.net/fix.php?id=35651&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=35651&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=35651&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=35651&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=35651&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=35651&r=dst IIS Stability: http://bugs.php.net/fix.php?id=35651&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=35651&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=35651&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=35651&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=35651&r=mysqlcfg
