func_get_arg

func_get_arg

(PHP 4 , PHP 5)

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.
