This is from a socket programming point of view, and has nothing todo with
php in particular (use the logic and map it to php)
your script freeze because it is opened by default in blocking mode:i.e.:
once you reach an end of data situation and you hit a read, the process
with obay you and wait untill something is available on that socket.
two situations you can remedy this:
1- convert the socket to non-blocking (this the call will return with an
error message of "no avaible data"
2- put your touches into the communication, and set in advance the amount
of data expected in ("a predefinded block/structure size"), so you'll be
building your own protocol into the communication say, ok I will send you
x amount of bytes, so read as much as x.
hope this help.
