Narrative:

We were cruising at 4000 ft and we got an RA for traffic 12 O'clock position 1 1/2 mi climbing to our altitude. We had no visual so we descended and turned right. In the turn, we saw the traffic (a helicopter). We notified ATC (phl departure) but they were not aware of the traffic. When we got on the ground, I called and spoke to the supervisor in phl and he said he would look into it.
