(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 this bug report at http://bugs.php.net/?id=32334&edit=1
