PHP IDE Roundup
The IDEs I've reviewed are just some of great IDEs available for PHP development. If you're still using a text editor with syntax highlighting for your PHP developement, you should really consider switching to an IDE - especially since some of them are free!
If you do PHP programming for a living, then you should already be using an IDE - consider looking at some of the more feature rich IDEs, it'll save you a lot of development time.
Alternatively, if you're just starting out in PHP, consider some of the free PHP IDEs, it'll be a steep learning curve, but you'll do yourself a favor in the long run.
