In respone to JimmyPaterson: Since the singleton method isn't declared final, you can override it in the children classes. First you have to change the singleton class a little to accept a classname parameter. class Singleton { // Hold an instance of the class private static $instance; // A private constructor; prevents direct creation of object private function __construct() { echo 'I am constructed'; } // The singleton method public static function singleton($classname) { if (!isset(self::$instance)) { self::$instance = new $classname; } return self::$instance; } } class SubClass extends Singleton { public static function singleton() { parent::singleton(__CLASS__); } } $singletonInstance = SubClass::singleton(); ---- Manual Page -- http://www.php.net/manual/en/language.oop5.patterns.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+51651 Delete: added to the manual -- http://master.php.net/manage/user-notes.php?action=delete+51651&report=yes&reason=added+to+the+manual Delete: bad code -- http://master.php.net/manage/user-notes.php?action=delete+51651&report=yes&reason=bad+code Delete: spam -- http://master.php.net/manage/user-notes.php?action=delete+51651&report=yes&reason=spam Delete: useless -- http://master.php.net/manage/user-notes.php?action=delete+51651&report=yes&reason=useless Delete: other reasons -- http://master.php.net/manage/user-notes.php?action=delete+51651&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+51651&report=yes Search -- http://master.php.net/manage/user-notes.php
