Do you want to learn PHP, or do you have a blog and just need some coding knowledge to manage your site? Have you tried reading through long PHP books, only to find the material draining and more than you'd ever need to know or could even possibly remember? I had those same problems. I wanted to master PHP, but knew that there had to be an easier way. I just needed a broad view of what was going on. Then, I was able to narrow down my needs, figure problems out, and grow from there. "PHP in 123" is meant to remove everything that you don't need to know about PHP and get you thinking and writing code ASAP. From there, you can effectively move towards your goals.
