PHP structure

[Thijmen]

Hi there @andrasbacsai,

I notice that some things in traits etc could be abstracted towards their own services. Some classes are doing a lot of stuff that it's not their 'core'-business. Therefore I would like to know if you would be open to accepting PR's that improve some of this infrastructure, aimed at usability and re-usability.

Plus doing this way would allow easier unit testing/integration testing in the future :)

Looking forward to your response.
