I downloaded the php. MySQL and the apache but, I am facing a problem in which the code is being displayed and not the web page. There must be a configuration problem.
Any help would be much appreciated.
What OS are you using? setup differs on linux, windoze and so on. Look up "installing LAMP on <your OS>" in google and you should find complete instructions. I have to say that trying to do it on windoze is a bit of a nightmare as i recall
Assuming that PHP and Apache are working correctly (and they may not be) then this is likely caused by trying to run PHP code from a module that doesn't have a .php suffix. For this reason or because of your setup, the module isn't being processed as a php module.
If you are using windows, it may be worth installing a virtual machine to run your lamp installation in. I remember trying to get it to work in windows a few years ago when I was still using it, and as I recall, I had similar problems, and never did work out how to fix them.
