certification study guide 
Well it finally showed up this weekend and man does it have a lot of information on areas I have never worked with. I can’t wait to get a chance to check it out…. *blush* along with all my other PHP books (I am currently reading 2 other PHP books on and off).
Will let you know if I find anything interesting. Since I’m self taught I’m sure there will be a million things in there that I had no idea about.
