Manual:DumpHTML.php

dumpHTML.php is a script that allows to make a simple HTML-dump of a MediaWiki installation.

You'll need a console-based command like  for Linux. You can't execute the file with your browser, because you aren't able to use parameters.

Parameters
For example (Linux): /usr/bin/php /opt/mediawiki/maintenance/dumpHTML.php -d C:\wikidump -k monobook

In MediaWiki 1.11.x images (and therefore also equations) are broken. See 12122 and 13061 for details. 1.11.x is the last branch to have dumpHTML.php as a maintenance script. For upcoming releases the functionality will be moved to an extension, http://svn.wikimedia.org/viewvc/mediawiki/trunk/extensions/DumpHTML/.
