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. Fixes #48082. git-svn-id: https://develop.svn.wordpress.org/trunk@47198 602fd350-edb4-49c9-b593-d223f7449a82
