You mean two randomly generated session IDs colliding? I think the
probability of it is pretty low. I mean it'd take PHP's random number
generator function to generate two equal random numbers in the same
microsecond. And these are random 64-bit numbers, so unless you're
generating billions of sessions per microsecond I don't think it's a
very real concern.
