Manual:Global object variables
From Linux Web Expert
Hundreds of globals are initialized on startup by MediaWiki. The majority of these global variables are configuration settings. (See Manual:Configuration settings for documentation on these variables.) There is no comprehensive documentation for the remaining few hundred globals, however, some of the most important ones are listed below. They are typically initialized either in index.php or in Setup.php.
