This should only be used to specify files that define $magicWords , $specialPageAliases , $namespaceNames . Its usage for $messages is deprecated.

Details

Associative array mapping extension name to the filename where messages can be found. The file must create a variable called $messages.

Example:

$wgExtensionMessagesFiles['ConfirmEdit'] = __DIR__ . '/ConfirmEdit.i18n.magic.php';

Changed behavior in MediaWiki 1.23

Since MediaWiki 1.23, use of this variable to define messages is deprecated; instead, store messages in JSON format and use $wgMessagesDirs . For setting other variables than $messages (such as $magicWords , $specialPageAliases , $namespaceNames ), $wgExtensionMessagesFiles should still be used.

If there is an entry in $wgMessagesDirs with the same key as one in $wgExtensionMessagesFiles, then any $messages variables set in the $wgExtensionMessagesFiles file will be ignored. This means an extension that only provides messages can be backward compatible by using both $wgExtensionMessagesFiles and $wgMessagesDirs, and only one of the two will be used depending on what the version of MediaWiki supports.
