Be very careful if fread() accepts user input. Even if you're just using it for URLs, a user
could view the contents of any file on your site or even server, depending on how it's set up.
All they have to do is put in a valid filename (ie - "./index.php"). If you're
allowing user input, you should AT LEAST verify that is_file() returns false before you display the
contents to the user.
