Let's assume you have configured nginx+Mediawiki like it's described here: http://wiki.nginx.org/MediaWiki.
I've noticed that it's impossinble to open a wiki article if its title contains ".php" substring. You check this here: http://wiki.nginx.org/test.php
You don't get Mediawiki warning about not existing page, all you can see is this warning: No input file specified.
This happens because nginx tries to pass requests to not-existing test.php script.
How should I configure nginx to be able to load such articles?
