Get file names from HTTP header

I'm sure someone has done this.

What I need to do is be able to connect to 2 different MySql databases on the same site.  The php/html is going to be the same.  My partner want's to change the data in his side of the site.

It's set up to load different databases on different servers and this does work.

Is there a way that I can get the info from the header on the web browser and then determine what data base that I should open?

If you mean "Can PHP detect which URL was used to access a common PHP script set?" The answer is yes.  Look in $_SERVER['HTTP_HOST']

Somehow I think in other way,  when you do http access on browser
and you have already known what url you want to type or go on browser.
 
There is a lot of $_SERVER variables you might need, please read this
http://www.php.net/manual/en/reserved.variables.server.php

Please tell us more detail of your question, so we could help you on exectly what you need.

I've read it the manual.  I can get the end of the url.  What it need to do is the the front of it.

IE:
http:\\langsystems.net\index.php

or

http:\\amy.langsystems.net\index.php

If I can get the line from the url, I can parse between the "http\\" and the first period  and get "amy" and then open the correct database.

I haven't resolved this yet.

There is one web site with a sub under it:

"langsystems.net"

"amelia.langsystems.net"

I need to change the database name to "amelia".
