Accessing quotes on the interface chillerlan\Database\Drivers\DBDriverInterface suggest that you code against a concrete implementation. How about adding an instanceof check?
                                                                                                                                                    

                    
                                            

                            

                            

                                
                                    
                                
                            


                            
If you access a property on an interface, you most likely code against a
concrete implementation of the interface.




Available Fixes


  1. Adding an additional type check:
    

    interface SomeInterface { }
class SomeClass implements SomeInterface {
    public $a;
}

function someFunction(SomeInterface $object) {
    if ($object instanceof SomeClass) {
        $a = $object->a;
    }
}

    

    

    2. 

  2. Changing the type hint:
    

    interface SomeInterface { }
class SomeClass implements SomeInterface {
    public $a;
}
