Narrative:

Aircraft X was westbound on the downwind assigned 5000 feet. Aircraft Y was released off of ffz assigned 3000 feet and 180 heading. After I radar identified aircraft Y there were numerous VFR aircraft in the vicinity appearing likely to converge with him. I climbed aircraft Y to 4000 feet. There were still numerous aircraft in their vicinity. I turned aircraft X to the north heading 350 and as soon as aircraft X was abeam aircraft Y I climbed aircraft Y to 5000 feet to avoid the several VFR aircraft they were conflicting with. I felt this was the safe way even though there may not have been 3 miles lateral separation with aircraft X.the only fix would be to lower the class bravo airspace.

Title: P50 TRACON Controller reported climbing an aircraft through the altitude of another aircraft with less than the required three lateral miles lateral separation to avoid numerous VFR aircraft.
