The following code causes about a 10 to 15 second delay/hang before finishing.  I'm not sure why it takes so long to read from the socket, the server here on our LAN returns a reponse to the initial fwrite() almost instantly...  I have a perl script that uses similar code and it's instantaneous.


$socket = fsockopen($h_addr, $h_port, &$errno, &$errstr);

$cmd = "arbitrary data";
fwrite($socket, $cmd, strlen($cmd));

while (!feof($socket)){
  $buffer .= fread( $socket, 1024);
}

fclose ($socket);
