#34462 [NEW]: isset($this->$x) no longer works when $x not set with PHP 5.05

From: bduclaux at yahoo dot com Operating system: Fedora Core 4 PHP version: 5.0.5 PHP Bug Type: Class/Object related Bug description: isset($this->$x) no longer works when $x not set with PHP 5.05 Description: ------------ PHP 5.05 modifies the handling of isset($this->$x) when $x is not set. This breaks many existing scripts, and is not properly documented IMHO. Reproduce code: --------------- <?php class A { function A() { $x=''; var_dump(isset($this->$x)); } } new A(); ?> With php 5.05 : Fatal error: Cannot access empty property in /home/sysop/test.php on line 5 With php 5.04: bool(false) -- Edit bug report at http://bugs.php.net/?id=34462&edit=1 -- Try a CVS snapshot (php4): http://bugs.php.net/fix.php?id=34462&r=trysnapshot4 Try a CVS snapshot (php5.0): http://bugs.php.net/fix.php?id=34462&r=trysnapshot50 Try a CVS snapshot (php5.1): http://bugs.php.net/fix.php?id=34462&r=trysnapshot51 Fixed in CVS: http://bugs.php.net/fix.php?id=34462&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=34462&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=34462&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=34462&r=needscript Try newer version: http://bugs.php.net/fix.php?id=34462&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=34462&r=support Expected behavior: http://bugs.php.net/fix.php?id=34462&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=34462&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=34462&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=34462&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=34462&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=34462&r=dst IIS Stability: http://bugs.php.net/fix.php?id=34462&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=34462&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=34462&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=34462&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=34462&r=mysqlcfg
