Author's Acknowledgments

I want to thank my mother for passing on a writing gene, along with many other things. And my children, always, for everything.

I wish to express my appreciation to the entire open-source community. Without those who give their time and talent, there would be no PHP and MySQL for me to write about. Furthermore, I never would have learned this software without the lists where people generously spend their time answering foolish questions from beginners.

And, of course, I want to thank the professionals who make it all possible. Without the people at Wiley, this book would not exist. Because they all do their jobs so well, I can contribute my part to this joint project.

Julian F.

Head of Cybersecurity

I wanted to learn C and C++, but it didn't click for me until I picked up an O'Reilly book. When I went on the O’Reilly platform, I was astonished to find all the books there, plus live events and sandboxes so you could play around with the technology.

Addison B.

Field Engineer

I’ve been on the O’Reilly platform for more than eight years. I use a couple of learning platforms, but I'm on O'Reilly more than anybody else. When you're there, you start learning. I'm never disappointed.

Amir M.

Data Platform Tech Lead

I'm always learning. So when I got on to O'Reilly, I was like a kid in a candy store. There are playlists. There are answers. There's on-demand training. It's worth its weight in gold, in terms of what it allows me to do.
