Details

• $title: the Title object
• &$pageLang: Language object or string; the page content language, either pass a Language object or a string (language code)

It was added in Title.php but is in content/ContentHandler.php since MediaWiki 1.21.

Example

For example, if you want to mark all pages in the namespace with index 200 (and its talk page 201) as being in French, use:

	static function onPageContentLanguage( $title, &$pageLang ) {
		if ( $title->getNamespace() === 200 || $title->getNamespace() === 201 ) {
			$pageLang = 'fr';
		}
		return true;
	}
