note 15996 added to language.variables.scope

In a large project recently undertaken, we have been using the PEAR virtual destructors. We have been using a small code snippet to allow pseudo-singletons within the OO code: class MyClass { function &getInstance() { static $instance = null; if ($instance === null) { $instance = new MyClass(); } return $instance; } } $myobj =& MyClass::getInstance(); However, this break PEAR destructors as $instance is created with new, rather than &new. If &new is used to create the static variable, it is destroyed on function exit, and therefore is null again the second time around. -- http://www.php.net/manual/en/language.variables.scope.php http://master.php.net/manage/user-notes.php?action=edit+15996 http://master.php.net/manage/user-notes.php?action=delete+15996 http://master.php.net/manage/user-notes.php?action=reject+15996
