Retrieving variables

Hi all, I'm attempting to store variables inside a database and then recall them. What I want to do is store them dynamically though - so for instance - a path to a file will be stored in the DB as $_SERVER[DOCUMENT_ROOT]."/path/to/file" But, obviously, when I retrieve this value, it retrieves it as a literal ... not much help because I want to parse it as a proper value. Is there any way to retrieve that value and then parse it within the PHP to create the "c:/webconsole/path/to/file" string that can be stored within another variable? Anybody got any thoughts?
