Aside: port is usually an integer not a string (unless you're giving a 
service name from /etc/services)

But the main problem is that socket.read will block until the other end 
drops the connection. You probably want socket.gets instead.

Other options include socket.readpartial(n) which will read *up to* n 
bytes, which you may have to repeat until you have the whole response; 
or if the protocol is length-framed, then use e.g. socket.read(4) to 
read the length, followed by socket.read(len). But that doesn't seem to 
be the case here.

I don't know the semantics of fread($fp,1000) in PHP, but from your code 
I'd guess it doesn't actually wait until 1000 bytes are available, but 
just reads up to 1000 bytes.

HTH,

Brian.
