The default PHP user agent is blocked; see Wikimedia's User-Agent policy for details. You can easily enough change your user agent using ini_set at the top of your script, like this:

ini_set("user_agent", "Testing for http://stackoverflow.com/questions/5509640");

Do note that the English Wikipedia forbids downloading many pages via the API (offering database dumps instead), and that automated processes that actually edit the wiki are forbidden unless approved. See their bot policy for details.

What do you need the file for? If you just need the output, you can try file_get_contents() instead, and then load and manipulate it as a string instead of a file.

The 403 error is coming from their server.

Chances are that you or someone on the IP address or block you are using has been aggressively banned from using the Wikipedia API. You will need to contact a responsible admin at Wikipedia to investigate.
