Working on a new MVC Application Framework i use this method to check how many arguments are required before calling the sub method!



Example 



<?php

        $this->method_args_count = $this->CReflection

            ->getMethod($Route->getMethod())

            ->getNumberOfParameters();

        //Maybe be 5 but if uri is /controller/method/single_param/ we only of 1

        $this->params = $Route->getParams(); //0 in some cases



        if($this->method_args_count > count($this->params))

        {

            $this->difference = ($this->method_args_count - count($this->params));

            for($i=0;$i<=$this->difference;$i++)

            {

                $this->params[] = false;

            }

        }

        

        //Call the method with correct amount of params

        // but as false for params that have not been passed!

        call_user_func_array(array(new $this->obj,$Route->getMethod()),$this->params);

?>
