Include Values Not Being Set

[Fubs]

When my page loads I am trying to include a number of files that contain site-wide settings, functions, and custom classes.

My main code does this:

include ('core/corelib.php');
include_all_PHPFiles('./php'); //Traverses the /PHP dir and Includes all PHP files
session_start();
echo "Username:".$mySQLuser;

One of the php pages sets up all of my global var's, and has the line:
$mySQLuser='foo';

If I echo $mySQLuser from the file itself, it is displayed on the screen (and session_start kicks up a fuss) - if I echo it from my main code it wont display anything. This is the same with all of my vars.

I have done this before, and cant see anything differant about this time, and its driving me nuts.

Any/All help appreciated

that seems to indicate a problem with your include_all_PHPFiles() function, or you're not pointing to the correct directory.

well the file is being included - because i can put an echo in the file and it will show it on the page.

There are only three files in the /php directory at the moment, and the other two are being included fine.

The include_all_php function is very simple:

Foreach file in directory
If file exists and extension is PHP
include file

its also recursive to include all subdirs.

I would post the code but I have turned off my DEV machine
