                                 func_get_arg

   (PHP 4 )
   func_get_arg -- Return an item from the argument list

Description

   mixed 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.

   <?php
   function foo() {
        $numargs = func_num_args();
        echo "Number of arguments: $numargs<br />\n";
        if ($numargs >= 2) {
        echo "Second argument is: " . func_get_arg(1) . "<br />\n";
        }
   }
   foo (1, 2, 3);
   ?>

   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.
