Ok, sorry I was so vague. I am running ubuntu on one computer and windows 7 on the other computer and I have the same problems. Here is the deal.
In windows when I try and open a php file all that is displayed in the window is the source code for the php file.
Now when I am using ubuntu, when I try and open the php file its asking me to save the file.
I do have xampp running and I am saving all my work to the htdcos folder.
I am able to view
http://localhost and I am also able to view
http://localhost/phpmyadmin.
So, what am I doing wrong, please help.
