Manually setting this variable to the absolute path to MediaWiki on disk from LocalSettings.php was necessary in older versions of MediaWiki. However, at least since MediaWiki 1.18, manually defining  in LocalSettings.php is no longer needed. It will default to the current working directory and it can be used without the need to define it manually. If there is an environment variable named MW_INSTALL_PATH defined, its value will be used instead.
