capturing user input

I have a MYSQL database set up. I also have a html form created. The
form requests' the users first and last names, address (with different
fields for town/state/zip), email and phone. I want to capture their
input directly into the database and I can't seem to find out how to.
It sounds fairly easy but I must not be looking in the right place as
I've been at it for about 8hrs now (it's 3 in the morning here in PA).
I've looked at the w3 site, tizag.com, phpfreaks, codewalkers,
php.net(?) and many more. If some one could point me in the right
direction I would GREATLY appreciate it.

Thanks

Neil
