PHP post.php mystery

I have a weird unexplainable phenomenon going on.

I downloaded some source code from a website, a basic PHP script. It came with an SQL to reference numbers as part of the script.

I uploaded the file called post.ph开发者_如何学Cp and SQL file to my server and ran it - but - instead of executing the code in the PHP file, it loads the content of the webpage of the author of the source code. and stays on my server URL.

The code in the file has nothing to do with the author's site, or graphics or links or redirects or anything.

EVEN IF I delete the entire contents of the post.php file, run the empty file and it STILL LOADS CONTENT from the author's website, where I downloaded it from.

Refreshed browser, restarted, reloaded, you name it. How is this physically possible?

-----UPDATE

In addition when I try renaming PHP files on my server, they become permanently broken "oops broken link" error.

It would be very helpful if you could post some more specific details about what the script was, etc. But, here is my guess. Firstly, make sure that your web server is not doing any caching. If the problem persists, try getting rid of the post.php file itself. Then, I would check to see if the PHP script has created any HTML/PHP files on its own. If all else fails, try going into the code that you downloaded and see what its doing.
