      5     echo "Number of arguments: $numargs<br>\n";
      6     if ($numargs >= 2) {
      7         echo "Second argument is: " . func_get_arg (1) . "<br>\n";
      8     }
      9     $arg_list = func_get_args();
     10     for ($i = 0; $i < $numargs; $i++) {
     11         echo "Argument $i is: " . $arg_list[$i] . "<br>\n";
     12     }

     15 foo (1, 2, 3);

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

> Note: This function was added in PHP 4.
