What is the good example of using 'func_get_arg' in PHP?

Question

I just have found out that there is a function called func_get_arg in PHP which enables developer to use variant style of getting arguments. It seems to be very us

Answer 1

Gets an array of the function's argument list.

This function may be used in conjunction with func_get_arg() and func_num_args() to allow user-defined functions to accept variable-length argument lists.

= 2) {
                echo "Second argument is: " . func_get_arg(1) . "\n";
            }
            $arg_list = func_get_args();
            for ($i = 0; $i < $numargs; $i++) {
                echo "Argument $i is: " . $arg_list[$i] . "\n";
            }
        }

        foo(1, 2, 3);
?>
