-msgid "Use fully qualified function names with leading backslashes to optimize opcache performance.  When calling [certain global functions](https://github.com/php/php-src/blob/944b6b6bbd6f05ad905f5f4ad07445792bee4027/Zend/zend_compile.c#L4291-L4353)  from within a namespace, PHP first searches in the current namespace before falling back to the global namespace.  Adding a leading backslash (e.g., `\\count()` instead of `count()`) tells PHP to directly use the global function, avoiding the namespace lookup and improving opcache efficiency. This optimization is best implemented automatically using tools like [PHP-CS-Fixer](https://github.com/FriendsOfPHP/PHP-CS-Fixer) with the `native_function_invocation` rule."
