We use VS 2005 with VS.PHP for vs2005 and we are very pleased with this product. With VS.PHP we can work and debug in paralel (2 or more programmers) on the same project. Combination with SourceSafe makes our work smooth and without gliches. InteliSense, good internal debugger with server, SourceSafe support, Zend Integrated...what can I say - good work.
The only thing missing, by my opinion, is that there is no spell check when you embed Javascript in html with tags. If there is such a thing - please inform me how to switch it on :)
We had a problem with the registration and the JCX team was very quick in its response to our problem - we were pleased.
Our company will continue to build its PHP.ERPs projects with VS.PHP :)
If you are building real PHP programs and you have VS in hand - VS.PHP is the solution.
God bless you JCX.
