What are your skills right now? Do you know some programming? PHP is easy to pick up if you know your "C" type languages, and if you know JavaScript or ECMA and your Java or C++, it's easy to pick up.
I don't do too much Database Web development (see DrLudicrous, Lady_Di, etc., for that), but I have dabbled into a lot of AUTOMATED PHP using Dreamweaver's scripts and some tweaking of my own. It's easy to create a MySQL connection, then a recordset and subsequently populate some pages with database query results in DreamWeaver.
Start at
W3Schools for easy reading on PHP, then move onto PHP.net for the real documentation. There are plenty of tutorials out there on MySQL and SQL database connectivity.
Good luck.
What exactly is a "long database", in your own definition? Is this for work? Check out some PHP beginner books at
www.bookpool.com if you can wait a couple of weeks for delivery, reading, etc.
