Help installing php on my computer

I need to be able to run, and test my scripts on my computer. I want to be able to click a file with the .php extension and have it automatically work within my browser. Can someone help me do this? It is really important that I get this help as soon as possible.

 

Check out xampp, with that you can run your own server on your pc.

 

the xampp is good like he said login or you can use

I just installed Xampp and everything but I still cant get the php files to run when I click them. Do you have any advice.

 

You have to save the files in your XAMPP directory, in:

[drive]:\Program files\XAMPP\htdocs\

Then you have to go to http://localhost/ and run the files from there.
