I use Measurement Protocol Parameter Reference in PHP to setup Google Analytics using PHP. For now all works fine only I can't figure out how to setup Timing.
In my GA dashboard session duration not work and I need to add that.
Here is reference of TIMING and I don't understand how to setup that.
Do I need to setup some sessions or I need to read __utma, __utmb, __utmc... cookies?
This is all in the initial stage but it works perfectly.
