Manual:Wg variable/ru

wg refers to an important non-constant programming element used in the MediaWiki software, and is an abbreviation for "Wikipedia Global" (the naming pre-dates the spread of MediaWiki beyond Wikipedia).

In general, any global variable (variable that has global scope) within the software has this prefix to make it easily identifiable when programming. However, a casual hacker will mainly come across such variables in the files  and , which define variables to control the behavior of the software in various ways.

The  file stores the defaults for these values and should not be edited; the   file is used to override these values for a specific site &mdash; if a particular variable is not mentioned in your   file, copy the entry from   and amend as appropriate.

Confusingly, MediaWiki code (mainly in ) and extensions set a different (though overlapping) set of configuration variables in browser JavaScript, and many of these variables also have a wg prefix (without PHP's   sign). See Manual:Interface/JavaScript for a list.

Starting with the introduction of the class in MediaWiki 1.23, the "wg" prefix for PHP global variables is being phased out as configuration settings are moving away from global scope.
