You should not use addslashes(). That does little to protect you.
You should at the very least use mysql_real_escape_string().

From a PHP perspective, make sure that you "clean" all of your inputs. You
should do this on the client side and also on the server side. Never trust
your data, and do not rely on Regular Expressions to clean your data. Stay
away from addslashes() as well, as that provides little protection. It may
still be possible to craft strings that will still evaluate properly to the
database. What I mean by that is when using SQL in PHP you should use
something like PDO (http://php.net/manual/en/book.pdo.php). With PDO you can
use bindings for all of your inputs. That will help prevent against SQL
injections. Hope that helps some.

I have written a php website. In this site I sell some license and
serial number. I need to protect serial numbers and user names and
passwords against sniffers and crackers. Now I want to secure this
site and encrypt sessions using https.
What do i have to do?

[1] mod_security is helpful. Teach it according to your requirement.
[2] From apache or .htaccess restrict bad robots
[3] rewrite rule to redirect non http to https

php should have some sort of security obviously. Have you implemented
those ?
php gurus can suggest more.
