Looking for help.

I need help. I am building a database for a collaborative non-profit organization. Originally it was scheduled to be done in MS Access, which I know fairly well. but the problem is they want it hosted on a freeDBS server and they do not have the ability to use an access database, nor are they willing to make the changes. So to make a long story short, I am now learning mysql and php. I has been a slow and often aggravating process, but we are starting to make some progress. But I need to learn more. Can anyone suggest a really good book, or possibly some tutorial classes I can on line that I can use to learn more about these programs. Thanks John
