I am a PHP web developer and to be honest I go to this site almost every day.
www.php.net/
I think it would be a great idea to take a class to get the basics but I am not sure it is completely necessary.

I tend to find the Visual Quickstart guides a good resource if you are just starting out. It might be because I am coming from a art background but I like how they give you examples of what you are doing through the whole book. www.amazon.com/PHP-MySQL-...343-5780123

Learn the basics of procedural programming then get into classes which make it object-oriented. First go with the basics like if/else statements, operators and expressions, global variables, then get into functions then classes and remember that if you think there should be a PHP function to do something...there probably is and you can find it at php.net.

Once you do that...then go get yourself a job making 80k.
