Say you want to keep track of the number of threads so that it doesn't go over, say, 6000 (imagine a client/server model where you only want 6000 concurrent connections). You'll probably want a variable indicating the maximum number of threads/connections, and a variable indicating the current number. Global variables -do- have their uses. But it's nice to have PHP's implementation where you specify which ones show up where. =)
