Unframework is the fastest PHP framework!
Actually, it's barely a framework, it is essentially just a few classes (most static) to handle initialisation and route a request to a specific file.
There are no controllers, no database models, no templating systems. It is designed to be as lightweight and fast as possible and not get in your way.
You are free to use whatever database system you want, which should be PDO.
You may think it's all a joke, and this website certainly makes it appear that way, but you won't be laughing when you see how much crap is involved when using something like Symfony or Laravel.
Such as needless middleware, bundles, compiling/caching. THIS IS PHP, NOT C++, all you should have to do is write some code and refresh the page, not spend time recaching everything.
Unframework is a serious project with a stupid name and website. Don't be afraid to use it.
