How to make OpenServer swear?

Question

open server

On my local server (OpenServer), if I include a folder with the wrong case or call a class with the wrong case, then there will be no error, how can I make it show an error?

class Test{
    public static function text(){
        return;
    }
}
test::text();

There will be no errors in such code, but it is necessary
