# func_get_args

(PHP 4, PHP 5)

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

### Description

array func_get_args ( void )

Gets an array of the function's argument list.

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

### Return Values

Returns an array in which each element is a copy of the corresponding member of the current user-defined function's argument list.

### Errors/Exceptions

Generates a warning if called from outside of a user-defined function.

### Examples

Example#1 func_get_args() example

`<?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);
?>`

### Notes

> Note: Because this function depends on the current scope to determine parameter details, it cannot be used as a function parameter. If you must pass this value, assign the results to a variable, and pass the variable.

> Note: This function returns a copy of the passed arguments only, and does not account for default (non-passed) arguments.
