Narrative:
Aircraft X was heading 350 degrees at 4;000 feet at PXR185005; air carrier Y was southbound; VFR at 3;500 feet at PXR270003; air carrier Y was 2 miles in trail of air carrier Z; also southbound and VFR at 3;500 feet. As soon as aircraft X checked onto my frequency I issued traffic; aircraft X responded that he had received an RA and was climbing. Aircraft X stopped the climb at 4;500 feet and descended back to 4;000. No further action taken by pilot. Recommendation; raise the satellite airspace ceiling to 6;000 over phx/pxr - this is an everyday occurrence in this block of airspace; multiple aircraft; both IFR and VFR; transit this area between 3;500 and 5;000 feet.

Narrative: Aircraft X was heading 350 degrees at 4;000 feet at PXR185005; Air Carrier Y was Southbound; VFR at 3;500 feet at PXR270003; Air Carrier Y was 2 miles in trail of Air Carrier Z; also southbound and VFR at 3;500 feet. As soon as Aircraft X checked onto my frequency I issued traffic; Aircraft X responded that he had received an RA and was climbing.
