I recommend giving this product a second look
I’ve been using Borland/Codegear products since the early days of Turbo Pascal some 25 years ago. Delphi for PHP 2.0 is a phenomenal improvement on version 1.0. Yes, it’s still a relatively new product, but the developers have achieved enormous strides forward in usability and reliability (and documentation). It is exactly what it purports to be: a rapid application development environment for php and as such it is unrivalled, in my opinion. Like anything new, it takes time to learn the basics but I’ve been using it now for close to a year and I love it.
If you’re interested in a familiar (to Delphi for Win32 users) environment which rewards you with fantastic productivity, I’d recommend taking a serious look at this version.
