This avoids the performance overhead of the function call every time `dirname( __FILE__ )` was used instead of `__DIR__`. This commit also includes: * Removing unnecessary parentheses from `include`/`require` statements. These are language constructs, not function calls. * Replacing `include` statements for several files with `require_once`, for consistency: * `wp-admin/admin-header.php` * `wp-admin/admin-footer.php` * `wp-includes/version.php` Props ayeshrajans, desrosj, valentinbora, jrf, joostdevalk, netweb.

* overriding the filters.
|

*
|
|
* The first filter, {@see 'themes_api_args'}, is for the args and gives the action

|
* an object is returned.
|

*
|
|
* The second filter, {@see 'themes_api'}, allows a plugin to override the WordPress.org
|
|
* Theme API entirely. If `$action` is 'query_themes', 'theme_information', or 'feature_list',
|
|
* an object MUST be passed. If `$action` is 'hot_tags', an array should be passed.
