# func_get_arg

func_get_arg -- Return an item from the argument list.

## Description

`int func_get_arg`(int arg_num);

Returns the argument which is at the `arg_num`'th offset into a user-defined function's argument list. Function arguments are counted starting from zero. func_get_arg() will generate a warning if called from outside of a function definition.

If `arg_num` is greater than the number of arguments actually passed, a warning will be generated and func_get_arg() will return FALSE.

      3 function foo() {
      4      $numargs = func_num_args();
      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 }

     11 foo (1, 2, 3);
     12 ?>

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

> Note: This function was added in PHP 4.
