On the PHPClasses website today, there's a new software review posted for the recently released Delphi for PHP from CodeGear (Borland).
He (Manuel Lemos) comes into the review not having dealt with Delphi before and having not created desktop applications before and found things a little overwhelming. He goes through the functionality of the application, including the structure of the applications you create (made up of "units" of PHP scripts). He gives a pretty comprehensive overview of what you can expect from the interface and a bit on some of the external functionality too - like the debugging.
For a first version of this PHP IDE, I think Borland/CodeGear did very well, but there is plenty of room for improvement. If you have been a big fan of Delphi for Windows desktop applications, you will certainly love Delphi for PHP.
Even if you dislike the choices that were made when it comes to the generated code or the library packages, Delphi for PHP may still be very useful for developers that need to quickly create a prototype of a PHP application and show how it looks to potential or current customers.
You can get more information, including features and pricing information from the official page on the CodeGear website.
