I did not found this discussion, so I will ask: why model methods like
null when no objects are found?
At least for me, this doesn't make any sense, because you have to prepare the application to handle objects and booleans. IMHO,
null is the right way to represent the lack of something, or you could write a method like this:
public function someMethod(SomeClass $someObject = false)
Extra shot: rewrite them to return
null will bring PHP7's null coalesce operator compatibility.
