An important part of being a PHP developer is knowing a little about server configuration, so we're going to start with a discussion of development server strategies and what options are available to you for professional hosting options.
As a fun exercise, try to find out what version of PHP you're currently using personally and/or at your company. We could discuss strategies for taking advantage of PHP's newest features when the pace of upgrading is often glacial and how to code with practices that make upgrades less painful.
As always, bring your beginner, intermediate, and expert-level questions and we'll have a go at answering them all in that order to the best of our collective abilities.
