Or a subprocess via exec() et. al.? For the former, the variable should (I think) carry over. For the latter, the stream number is going to be a meaningless value to the subprocess. ((e.g. stdin (fd=0) for the parent is a different source than stdin for the child, despite being the same number)). I'm not sure of your exact use case, but you might be able to use proc_open to spawn the child and supply the socket in the descriptor spec which will (I think, iirc) bind the internal socket to a new pipe between the parent and child. Though it's possible you'll need to maintain a proxy loop in the parent. 40% of the above is guesswork and conjecture, but maybe it'll spawn the right question. -Sara
