[PHP] Subtracting Large Numbers

I am puzzled by the following code: MaxInt=".PHP_INT_MAX; $AA = -190668411; $BB = -2181087916; print "AA=$AA"; print "BB=$BB"; $AA = (int)$AA + (int)$BB; print "AA+BB=$AA"; ?> On some systems, I get: MaxInt=2147483647 AA=-190668411 BB=-2181087916 AA+BB=-2338152059 On others, I get: MaxInt=2147
