$ready contains the number of sockets on which the state has changed.
The code which you posted goes through the loop $ready times, accepting
$sock and putting the result in an empty $client[$i]['sock'].
This is a hard example. It is probably best to try out socket_select
with just one socket. Try what it does and what its return value is.
