For example suppose I have a Car object and I want my array to consist only of Cars. Is there some syntax that allows me to do this?

No. PHP does not have any strong typing.
The only way I can think of enforcing this would be to have a CarArray class that has getters,setters,etc.. functions that enforce the parameters to be of class Car.
