Config is the base interface for implementations that provide access to read various configuration settings. To get the default implementation, use MediaWiki\MediaWikiServices::getInstance()->getMainConfig(), MediaWiki\MediaWikiServices::getInstance()->getConfigFactory()->makeConfig( 'main' ) or RequestContext::getMain()->getConfig().

Available implementations in core are:

• GlobalVarConfig — can access settings in the $GLOBALS superglobal array.
• MultiConfig — can contain multiple config objects that are acting as fallback sequence.
• HashConfig — stores the configuration in a member variable, allowing values to be set, rather than only get.

Methods

• get( $name ) — returns the value of the configuration value named, $name; throws a ConfigException if not set.
• has( $name ) — returns true or false depending if the config object has the configuration value named, $name stored.
