retrive the function arguments in php

The func_get_args() function returns an array of argument that a function has in it's parameter list. There are also func_num_args() and func_get_arg() functions which can be used to get function parameter information. let's see zend mock certification test question below.

What would you replace ??????? with, below, to make the string Hello, World! be displayed?


1. There is no way to do this
2. $string = $argv[1];
3. $string = $_ARGV[0];
This will return the script name.
4. list($string) = func_get_args();
5. $string = get_function_args()
