Having Difficulty passing variables through includes using globals - php

Question

I have a three tier tree for displaying content on a page. It uses includes to display specific PHP pages based on the URL. What doesn't happen is the variables are not understood in included PHP files.
index.php
// example url http://fakesite.com/?color=red&user=999
$user = $_GET['user'];
if ($_GET['color'] == 'red')
{$color = 'red';}
elseif ($_GET['color'] == 'white')
{$color = 'white';}
else
{$color = 'blue';}
global $color;
global $user;
include 'page2.php';
page2.php
global $color;
global $user;
echo 'hi '.$user.'I hear you like '.$color;

Answer 1

There is no need at all for those $global lines. Any variables defined in the main script are defined in the included file. It's basically like taking the code in the included file and shoving it in the place of the include call (with a few exceptions)

Answer 2

This line:
include_once 'page2.php;
should change to:
include_once 'page2.php';
You have a missing quote.

Answer 3

Have you tried removing ALL those four global lines? I don't know if that's the problem, but they're not necessary at all!
When including or requiring a file all the variables declared above are available to the included/required file.
If that didn't solve it, maybe you have the wrong path on include.

Answer 4

index.php
<?php
$user = $_GET['user'];
if ($_GET['color'] == 'red')
{$color = 'red';}
elseif ($_GET['color'] == 'white')
{$color = 'white';}
else
{$color = 'blue';}
include 'page2.php';
?>
page2.php
<?php
echo 'hi '.$user.'I hear you like '.$color;
?>
global example
function dosomethingfunky(){
global $user, $color;
echo 'hi '.$user.'I hear you like '.$color;
}
