使用PHP通过套接字向系统传递数据

我有下面的示例数据流，它必须通过套接字编程传输到系统。此流是从数据库生成的。每243个字符，我就会得到一个新的流。

>  0243P254NIP40524KCK0240000000104844200001               
> 00000064005736540000000985714052400000000000010000000000000000BIR01082013KCK*IBKL0KCK01*130718i28535983*lazy

我尝试了下面的代码，但我如何读取流并将响应映射到输入。

每次我收到下面的消息from server.php"无法读取输入"from client.php"无法将数据发送到服务器"

请告诉我如何让服务器php读取数据，让客户端php发送数据

server.php
<?php
$host = "217.16.1.12";
$port = 10001;
$message = "Hello Client";
set_time_limit(0);
// create socket
$socket = socket_create(AF_INET, SOCK_STREAM, 0) or die("Could not create socket'n");
// bind socket to port
$result = socket_bind($socket, $host, $port) or die("Could not bind to socket'n");
// put server into passive state and listen for connections
$result = socket_listen($socket, 3) or die("Could not set up socket listener'n");
// accept incoming connections
$com = socket_accept($socket) or die("Could not accept incoming connection'n");
// read client input
$input = socket_read($com, 1024000) or die("Could not read input'n");
// clean up input string
$input = trim($input);
echo "Client says: ".$input;
socket_write($com, $message , strlen ($message)) or die("Could not write output'n");
// close sockets
socket_close($com);
socket_close($socket);
?>
client.php
<?php
include ("db/Config.php");
$host    = "217.16.1.12";
$port    = 10001;
$data = mysql_query("select isbn from klrans where isbn is not NULL and isbn <> '' limit 5");
while($info = mysql_fetch_array( $data )) 
         {
          $ifsc= $info['isbn'];
         $msg .=  "<td align='center'>".$isbn. "</td> "; 
         } 

$message = $msg;

// create socket
$socket = socket_create(AF_INET, SOCK_STREAM, 0) or die("Could not create socket'n");
// connect to server
$result = socket_connect($socket, $host, $port) or die ("Could not connect to server'n");
// send string to server
socket_write($socket, $message, strlen($message)) or die("Could not send data to server'n");
// get server response
$result = socket_read ($socket, 1024000) or die("Could not read server response'n");
echo "Server  says :".$result;
// close socket
socket_close($socket);
?>
