# func_get_args

(PHP 4 )

func_get_args -- Returns an array comprising a function's argument list

## Description

array func_get_args ( void )

Returns an array in which each element is the corresponding member of the current user-defined function's argument list. func_get_args() will generate a warning if called from outside of a function definition.

`<?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"; } $arg_list = func_get_args(); for ($i = 0; $i < $numargs; $i++) { echo "Argument $i is: " . $arg_list[$i] . "<br />\n"; } } 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.

> Notatka: This function was added in PHP 4.
