include

I would like to ensure that any scripts that are trying to "include" my database connection file are located under my own domain. I don't want a hacker to include the database connection file to their malicious script and gain access to my database that way. My connection file's name is pretty easy to guess, it's called "connect.php". So without renaming it and taking the security through obscurity route, how can I protect it by making sure all connection requests are made by scripts residing under my own domain name? How can this be checked using PHP?
