URL とファイル パス: $IP
導入されたバージョン:pre 1.1.0
既定値:MW_INSTALL_PATH 環境変数 (設定されていない場合は、カレント ディレクトリ)。

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 $IP in LocalSettings.php is no longer needed and no longer works as you may expect. It will default to the current working directory and it can be used without the need to define it manually.

If you have to override the default value you have to declare the environment variable MW_INSTALL_PATH. See the documentation of your webserver for how to do it.

Note that you can't just override $IP from your LocalSettings.php if you do not want to fix also all the variables that are based on it, like $wgExtensionDirectory etc.


IP は Include Path を表します。この変数はウィキのインストール先のベースであるローカル ファイル パスを保持します。既定値を上書きするいかなる理由がある場合でも、完全なファイル パスを使用していることを確認してください。パスの末尾にスラッシュを含めないでください。

In MediaWiki 1.16 and prior, where the DefaultSettings.php file still had to be loaded from inside LocalSettings.php, the directory to load it from was determined by the IP variable.

他の変数とは異なり、既定値は DefaultSettings.php ではなく WebStart.php で設定されています。

Setting the MW_INSTALL_PATH environmental variable can sometimes be useful when running maintenance scripts that are in non-standard directories. (Maintenance scripts by default use the parent of the current working directory as $IP).
