One of the best approaches to explain the usage of the class to a foreign developer and to be sure that your class is used correctly and help the foreign developer to understand how your classes have to be used (beside documentation), is to typehint your parameters. But when you do so, you are no longer able to overload your methods anymore. Because of this, I think this feature is EXTREMELY relevant to solving the web problem. Not being able to overload methods anymore is a bad thing since overloaded methods allow to use a class in much more situations than just being able to use it in one single way. You are not able to tell the developer to use integer OR string values but NO arrays, booleans, Objects and so on when calling your method. You could mention it in the comment but when he misunderstands the comment, php doesn't notify him about his error. When using type hinted parameters, php would do so. You are not able to provide strict api's out of the box right now. You will always have to check the types of the passed parameters manually.
