You can't just copy and paste code you find on the internet. You need to understand what the code does and how to adapt it to your environment. As a help forum you need to post your code here (using the code icon (<>) in the top menu specifying PHP or HTML as appropriate) along with any error messages and/or what output you expect that is different from what you actually get. The first place to start is to make sure your httpd is running properly. What files are currently in your DocRoot?
