    Terrific time-saver

    I found this book surprisingly useful as an ordinary PHP user. I thought it might be only for gurus, but when I picked up the book it fell open to a function that could have saved me hours of programming on a previous project. I didn't know the function already existed. That's what's great about this book. There are hundreds of PHP functions, the vast majority of which are unknown to the casual user. If you're on deadline there isn't time to learn them all, or to wander the PHP sites until you hit paydirt. This book simply lays them out, with a clear description and example attached to each. It's a huge time-saver.
