Are there best practices for passing objects to other objects in PHP?

When passing objects to other objects in PHP, it is a good practice to use type hinting to ensure that the correct type of object is being passed. This helps in preventing unexpected errors during runtime. Additionally, passing objects by reference can be more efficient than passing by value, especially for large objects. 

class ObjectA {
    public function doSomething(ObjectB $objectB) {
        // code here
    }
}

class ObjectB {
    // code here
}

$objectA = new ObjectA();
$objectB = new ObjectB();
$objectA->doSomething($objectB);
