Security question about mysql connect

[music_lp90]

I have a php page that has my connection script to connect to my mysql database and I include it on any page that I need to connect to the database with. Can someone use that page to gain access to my database by typing in the url to that connection page? Something like www.whatever.com/connection_page.php. I'm guessing probably not, because I think this is a common thing that developers do, but maybe they protect it somehow. Thanks for your help!

Other scripts on the same server would be able to include it, but anyone trying to include a file using http would get the results of the file. Open the file yourself in a browser to see what someone would be able to include from another server.
