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
See the documentation of your webserver for how to do it.
IP stands for Install Path. The variable holds the local file path to the base installation of your wiki. If for whatever reason you want to overwrite its default - make sure you refer to the fully qualified file path. Do not include a slash at the end of the path.
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.
A diferencia de otras variables, el valor predeterminado se establece en WebStart.php en vez de DefaultSettings.php.
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).
