I'm trying to get my head around Dependency Injection and I understand it, for the most part.
However, say if, for some reason, one of my classes was dependent on several classes, instead of passing all of these to this one class in the constructor, is there a better, more sensible method?

right direction would be fantastic.
If you have several dependencies to deal with, then yes a DI container can be the solution.
The DI container can be an object or array constructed of the various dependent object you need, which gets passed to the constructor and unpacked.

benefit to using an object instead of an array is that by default it will be passed by reference into the classes using it, while an array is passed by value (though objects inside the array are still references).
