PHP is an incredibly powerful and versatile scripting language. PHP is also an essential skill for most web developers: it's used today by four out of five websites and by more than half of the world's top 1,000 sites. As a result, the PHP community\ is large, active, and vibrant, and it's a magnet for smart developers and technologists.
The following list—in alphabetical order—includes some of the most prominent PHP source and framework committers, project leaders, teachers, visionaries, and entrepreneurs. Follow their blogs, Twitter feeds, and other communication channels to get a front-row view of what matters to the community today, where it wants to go, and how you might be able to get involved.
