        public function __construct($callback/*[, $arg1][, $arg2][, $argN]*/) {
                $this->args = func_get_args();
                $this->callback = array_shift($this->args);
        }
       
        public function __invoke(/*[, $arg1][, $arg2][, $argN]*/) {
                $moreArgs = func_get_args();
                $args = array_merge($this->args, $moreArgs);
                return call_user_func_array($this->callback, $args);
        }
       
}

$world = new CurriedFunction('substr', 'Hello World.', 6);
echo $world(); // World.
echo '<br />';
echo $world(1); // W
