PHP Trying to Use a Namespaced Function (Not Class)

Question

I'm running PHP 5.6.24 and as far as I understand, I should be able to do this:

functions.php

<?php
namespace lib;

function test_function ($var) {
    echo $var;
}
?>

<?
require 'functions.php';

use lib\test_function;

test_function('Hello, world!');
?>

However, I get a Fatal error: Call to undefined function test_function()

What am I doing wrong?

if you're not sure what version of php you are running go ahead and write a script that just has phpinfo(); in it. and look through it. — Teddy Codes

Look at the first example: php.net/manual/en/language.namespaces.basics.php — Teddy Codes

If you would like to use a function, you have to do something like this:

use function lib\test_function as func;
func("Hello World!");

Hope this helps!

That was it! I needed to add the keyword "function" after "use." Thank you!
