肯定的：

$fp = fsockopen("tcp://example.com", 8888) OR die("could not connect"); 
while (!feof($fp)) { 
    $pc = fread($handle, 8192); 
    if ($pc === false || strlen($pc) == 0) 
     break; 
    //a new packet has arrived 
    //you should collect the read in a variable and wait 
    //for another packet until you know the message is complete 
    //(depends on the protocol) 
    collect_in_result($pc); 
    if (message_is_complete()) { 
     if (check_event()) { 
      //take action 
     } 
    } 
}
