note 125686 added to xml.installation

Trying to look at the Oolite wiki, I was diverted to a page reading: ______________________________________________________ MediaWiki 1.31 internal error Installing some PHP extensions is required. Required components You are missing a required extension to PHP that MediaWiki requires to run. Please install: xml (more information) _______________________________________________________ Clicking on (more information) brought me here. Don't understand a word of the gubbins on this page. A complete mystery. "More information" for somebody with silicon chips for a brain, maybe, but not for an ordinary human being! No idea what PHP is. No idea what an xml is. No idea what a parser is. Or how to download whatever I'm supposed to download. ---- Server IP: 45.112.84.4 Probable Submitter: 45.91.159.166 (proxied: 91.125.98.227) ---- Manual Page -- http://php.net/manual/en/xml.installation.php Edit -- https://master.php.net/note/edit/125686 Del: integrated -- https://master.php.net/note/delete/125686/integrated Del: useless -- https://master.php.net/note/delete/125686/useless Del: bad code -- https://master.php.net/note/delete/125686/bad+code Del: spam -- https://master.php.net/note/delete/125686/spam Del: non-english -- https://master.php.net/note/delete/125686/non-english Del: in docs -- https://master.php.net/note/delete/125686/in+docs Del: other reasons-- https://master.php.net/note/delete/125686 Reject -- https://master.php.net/note/reject/125686 Search -- https://master.php.net/manage/user-notes.php
