I found Delphi can write php web application as well. As well as, all others Modern Web Programming Language. Delphi for php has event-driven and RAID by using their own framework.I have watched their presentation, it is cool, but too short, a minute long. Click here to view.
I have installed to two instances of egroupware.
One is on the server in web hosting company, this is using PHP 4.33.
Sometime, it will have HTTP 500 errror.
But in my PHP 5.1 server, that is complete good.
