Hi, I have tried Microsoft webmatrix, It is very good. Is there any way to debug the PHP script ? If debugging PHP script is supported, then it will be a great IDE for PHP. If you dont know about WebMatrix, Check it here. http://www.microsoft.com/web/webmatrix
I think running PHP itself gives enough debugging errors/warnings line by line. Would you still need an IDE for it? echo ""; is the best I have found till now for debugging. But, I'll definitely have a look at your link.
