While developing a website or web application, I used to upload the entire website in to a remote server before I could test it. This was very difficult, time consuming and expensive. I was waiting looking for an ideal solution where I could develop and test applications in my local computer while having all the benefits of a remote server. Xaamp is really useful to me as it really helps in developing and testing web application in PHP , also databases that are mySQL compliant. The only difficulty I had was I could not run my IIS or skype while using Xaamp. now I learned to edit the configuration file to change the port used by Apache, hence I can have them all running concurrently. Thank you Xaamp Mobs
