To get round this problem, another option is a factory to create singletons. <?php class Factory { private static $instances = array(); public static function getInstance($class_name) { if(!array_key_exists($class_name, self::$instances)) { self::$instances[$class_name] = new $class_name(); } return self::$instances[$class_name]; } } ?> I guess you could modify this to create singletons from some, and prototypes for the rest. There's probably some good way to stop people instantiating objects directly. Perhaps by using the backtrace in the constructor of the class to ensure that it was indeed the Factory that created the object. ---- Server IP: 193.95.141.37 Probable Submitter: 83.70.255.66 ---- Manual Page -- http://www.php.net/manual/en/function.get-class.php Edit -- https://master.php.net/note/edit/83984 Del: integrated -- https://master.php.net/note/delete/83984/integrated Del: useless -- https://master.php.net/note/delete/83984/useless Del: bad code -- https://master.php.net/note/delete/83984/bad+code Del: spam -- https://master.php.net/note/delete/83984/spam Del: non-english -- https://master.php.net/note/delete/83984/non-english Del: in docs -- https://master.php.net/note/delete/83984/in+docs Del: other reasons-- https://master.php.net/note/delete/83984 Reject -- https://master.php.net/note/reject/83984 Search -- https://master.php.net/manage/user-notes.php
