hey guys I found easy software to run php http://sourceforge.net/project/showfiles.php?group_id=14045
I was running WAMP on my Windows based PC when I was a newbie. Here is the link http://www.wampserver.com/index.php?lang=en
I use XAMPP from www.apachefriends.org It even has a switcher that makes it easy to switch between PHP4 and PHP5.
I didn't realize this thread was about AMP servers. I've always liked the XAMPP package from apachefriends as a good windows package. These days, I usually just connect to my web host by SSH and write code there. This has the benefit of allowing you to write code and not worry about compatibility, as there are sometimes problems in transferring code from different servers. Probably the best solution to writing code on a local machine is to get an easy to use Linux distribution like Ubuntu. I'm guessing that most of us host our sites on Linux servers, so it seems like it would make sense to develop on a Linux server. Also, I recently found an application called PHP Interactive, which is described as a web based interactive shell for PHP. I haven't had much time to play around with it, but it looks pretty neat.
