We had received a clearance from PHL ground to taxi to hold short of rwy 27r; via taxiway kilo3. We were not told to give way to any aircraft on our way to hold short of 27r. I noticed that there was a Regional Jet taxiing on taxiway kilo; east bound towards taxiway kilo 3. I slowed and stopped to ensure there would be no conflict with the Regional Jet. I saw the Regional Jet stop just prior to the intersection of taxiway kilo 3 and kilo. I intended to ask my co pilot to confirm with phl ground that we had right of way to taxi; when I saw the Regional Jet start taxiing again. My aircraft was past taxiway Juliet; on kilo 3; holding short of taxiway kilo. The Regional Jet started turning left; in to kilo 3. I turned on my taxi/landing light and yelled 'STOP!' on the ground frequency as the Regional Jet continued his turn in to me. The Regional Jet moved to the far right of taxiway Kilo 3; far to the right of the yellow taxi line. The Regional Jet's left wingtip passed within feet of the radome on my aircraft. The incident occurred because [the other aircraft] was incredibly reckless and dangerous in the operation of his aircraft. There was no obstruction by my aircraft on taxiway kilo. He could have continued his taxi straight ahead; or after turning in to kilo 3 could have stopped and had tugs clear us apart.
A320 Captain taxiing at PHL reported a Regional Jet deviated from his clearance and taxied dangerously close to his aircraft.
