Bug introduced by
It seems like $configuration is not always an object, but can also be of type null. Maybe add an additional type check?

If a variable is not always an object, we recommend to add an additional type check to ensure your method call is safe:

function someFunction(A $objectMaybe = null)
{
    if ($objectMaybe instanceof A) {
        $objectMaybe->doSomething();
    }
}

Bug Best Practice introduced by
The return type of return array(); (array) is incompatible with the return type declared by the interface TechDivision\Import\Loaders\LoaderInterface::load of type ArrayAccess.

If you return a value from a function or method, it should be a sub-type of the type that is given by the parent type f.e. an interface, or abstract method. This is more formally defined by the Lizkov substitution principle, and guarantees that classes that depend on the parent type can use any instance of a child type interchangably. This principle also belongs to the SOLID principles for object oriented design.

Let’s take a look at an example:

class Author {
    private $name;

    public function __construct($name) {
        $this->name = $name;
    }

    public function getName() {
        return $this->name;
    }
}

abstract class Post {
    public function getAuthor() {
        return 'Johannes';
    }
}

class BlogPost extends Post {
    public function getAuthor() {
        return new Author('Johannes');
    }
}

class ForumPost extends Post { /* ... */ }

function my_function(Post $post) {
    echo strtoupper($post->getAuthor());
}

Our function my_function expects a Post object, and outputs the author of the post. The base class Post returns a simple string and outputting a simple string will work just fine. However, the child class BlogPost which is a sub-type of Post instead decided to return an object, and is therefore violating the SOLID principles. If a BlogPost were passed to my_function, PHP would not complain, but ultimately fail when executing the strtoupper call in its body.
