Question

I’ve got a scope problem here. and no idea why its not working, ive got a setup as follows:

functions.php

global $id;
$id = $_GET['id'];

index.php

require_once('functions.php');
echo $id;

now inside functions.php i can echo out $id. however my echo $id; inside index.php is bringing up blank. absolutely nothing.

what am i doing wrong?

You don’t need globals between files, only for functions.

Functions.php

<?php
$foobar = "Hello";
?>

Index.php

<?php
include('Functions.php');
echo $foobar;
?>
