I understand your urgency, and yes sometimes the manuals aren't the best way to learn. But never leave your PHP/MySQL manuals alone, sleep with them under your pillow!
Don't think you'll be able to dive feet first into this and get the project done; you won't. You will crash and burn. Allow yourself the time to learn, or if time is short, do it in a langauge you already know.
Once you allocated time, go through the PHP articles here at PHPBuilder and at Devshed (www.devshed.com). They are the best way to learn.
Although we'd all love to be able to help you step by step through your learning process, it's just not a viable option.
If you get stuck along the way, and neither the tutorial you are using, nor the manual helps, then come back here and post a message.
Good luck!
