Including global.php clears all my variables

I've been including global.php from a script in another directory in order to access $vbulletin login information. However, I've realized global.php keeps clearing any variables I set and the only way to keep them around is to store them in a session. Why is it doing this, and is there a way I can make it stop? Thanks.

What variables? Superglobals?

I'm not particularly advanced in PHP. All I know is that anything I set before requiring globals.php gets unset after the include.

I found a thread dating to 2004 in which a vB staff member said

I believe this is what I mean.

If I were to do the following…

PHP Code:


		
			
$var='value';
require('/home/dir/www/forums/globals.php');
echo $var;

…$var would return empty.

Then.... include global.php at the beginning of your page before you set the variables?

Yes, this is the solution I ended up using, though it's a bit of a pain because previously it was in my header include; now it has to be inserted at the top of every page by itself.

Thanks.
