#32334 [NEW]: __set acts unexpected with variable variables

From: mk at peytz dot dk Operating system: Linux PHP version: 5.0.3 PHP Bug Type: Zend Engine 2 problem Bug description: __set acts unexpected with variable variables Description: ------------ When setting variable variable values on a instance of a class with an overloading __set function changing another instance variable goes wrong. (I'm reporting it for version 5.0.3 because the current cvs snapshot would not compile.) Reproduce code: --------------- http://dev.peytz.dk/~mk/setter.php <?php class Setter { private $_fields = array(); // the data fields private $_changedFields = array(); // list of changed fields function __set($name, $value) { // set value $this->_fields[$name] = $value; // add to list of changed fields $this->_changedFields[] = $name; } } $foo = new Setter; $foo->a = 1; $var = "b"; $foo->$var = 2; var_export($foo); ?> Expected result: ---------------- class Setter { private $_fields = array ( 'a' => 1, 'b' => 2, ); private $_changedFields = array ( 0 => 'a', 1 => 'b', ); } Actual result: -------------- class Setter { private $_fields = array ( 'a' => 1, 'b' => 2, ); private $_changedFields = array ( 0 => 'a', 1 => '›‡ˆ', ); } -- Edit bug report at http://bugs.php.net/?id=32334&edit=1 -- Try a CVS snapshot (php4): http://bugs.php.net/fix.php?id=32334&r=trysnapshot4 Try a CVS snapshot (php5.0): http://bugs.php.net/fix.php?id=32334&r=trysnapshot50 Try a CVS snapshot (php5.1): http://bugs.php.net/fix.php?id=32334&r=trysnapshot51 Fixed in CVS: http://bugs.php.net/fix.php?id=32334&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=32334&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=32334&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=32334&r=needscript Try newer version: http://bugs.php.net/fix.php?id=32334&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=32334&r=support Expected behavior: http://bugs.php.net/fix.php?id=32334&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=32334&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=32334&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=32334&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=32334&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=32334&r=dst IIS Stability: http://bugs.php.net/fix.php?id=32334&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=32334&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=32334&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=32334&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=32334&r=mysqlcfg
