[php] Varible declaration

Hi, when I declare the varible $cid like this "http://myserver/index.php?cid=1" it works fine, but when i declare it in the code like this $cid = '1'; it doesn't work... is this maybe because of the level i declare the varible? how to i declare it the same as "http://myserver/index.php?cid=1" but in my php code... PS. I use this varible in a function that is called by a function wich is included and so on... it is rather far down.
