I would like to start blogging using WordPress. I've heard that my ISP needs to support PHP and MySQL in order for this to work? I have no idea what either is but I have seen a few examples of small test-files (info.php) I can upload to my site and attemp to view them in order to find out if my ISP supports it. Always when I try this my browser only shows the content of the file itself as code, nothing else. What does that mean?
