I'm running three MediaWiki sites, and I copy the PHP files from folder to folder. Can I run them somehow from the same PHP files, so I won't need to copy and update all the files three times? By the way, how do you do that in Wikimedia sites - copy the PHP files, or using the same ones? And how do you do that?
(Of course, using different LocalSettings.php for every site, and running from other folders.)
