Extensions: $wgExtensionMessagesFiles
Extension messages files.
Introduced in version:	1.11.0
Removed in version:	Still in use
Allowed values:	(array)
Default value:	`[]`
Other settings: Alphabetical \| By function

This global variable must only be used to specify the paths to internationalization files that define magic words , special page aliases and/or namespace names .

For message files , use $wgMessagesDirs instead and avoid overlap in variable names. If there is an entry in $wgMessagesDirs with the same key as one in $wgExtensionMessagesFiles, $wgMessagesDirs will take precedence over the other.

Example

The ConfirmEdit extension contains a PHP file, ConfirmEdit.alias.php, which defines language-specific aliases for a special page (Special:Captcha). If the extension were to define the variable directly in PHP, it would have something like this:

$wgExtensionMessagesFiles['ConfirmEditAlias'] = __DIR__ . '/ConfirmEdit.alias.php';

extension.json

Instead of using our global variable directly, modern extensions like ConfirmEdit set the equivalent field ExtensionMessagesFiles in the extension.json file. This field corresponds directly with $wgExtensionMessagesFiles :

	"ExtensionMessagesFiles": {
		"ConfirmEditAlias": "ConfirmEdit.alias.php"
	},
