PHP class name constant (::class) is case insensitive and that might break your PSR-11 container access

PHP´s magic ::class-constant will not canonical the casing of your imports.

This can lead to hard to debug errors when you a using a case sensitive service PSR-11-locator like Zend\ServiceManager.

# You should avoid using .htaccess files completely if you have

# slows down your Apache http server. Any directive that you can
