    Abstracted Singleton

    Is there a way to abstract the singleton so that one can derive from it? I've not been able to get this working. Thanks!

    No, but my typically argument is: A singleton is only a few lines of code, isn't there a more complelling object hierarchy for you to inherit from?

    You can use a registry.
    PHP Code:
    class Registry
    {
        function & 
    GetInstanceOf($class) {
            var 
    $instances = Array();
            if (!isset(
    $instances[$class])) {
                
    $instances[$class] =& new $class();
            }
            return 
    $instances[$class];
        }
