用PHP的socket实现客户端到服务端的通信实例详解

一、server.php服务端：<?phperror_reporting(E_ALL);set_time_limit(0);ob_implicit_flush();//本地IP$address=

一、server.php服务端：

<?php 
error_reporting(E_ALL); 
set_time_limit(0); 
ob_implicit_flush(); 
//本地IP 
$address = 'localhost'; 
//设置用111端口进行通信 
$port = 111; 
//创建SOCKET 
if (($sock = socket_create(AF_INET, SOCK_STREAM, SOL_TCP)) < 0) { 
 echo "socket创建失败原因 " . socket_strerror($sock) . "\n"; 
} 
 
if (($ret = socket_bind($sock, $address, $port)) < 0) { 
 echo "创建套接字失败原因 " . socket_strerror($ret) . "\n"; 
} 
//监听 
if (($ret = socket_listen($sock, 5)) < 0) { 
 echo "监听失败原因 " . socket_strerror($ret) . "\n"; 
} 
do { 
 //接收命令 
 if (($msgsock = @socket_accept($sock)) < 0) { 
 echo "命令接收失败原因: " . socket_strerror($msgsock) . "\n"; 
 break; 
 } 
 $msg = "\nPHP Test Server. \n" ."用quit,shutdown,sun...等命令测试.\n"; 
 
 @socket_write($msgsock, $msg, strlen($msg)); 
 
 do { 
 if (false === ($buf = @socket_read($msgsock, 2048, PHP_NORMAL_READ))) { 
 echo "socket_read() failed: reason: " . socket_strerror($ret) . "\n"; 
 break 2; 
 } 
 if (!$buf = trim($buf)) { 
 continue; 
 } 
 if ($buf == 'quit') { 
 break; 
 } 
 if ($buf == 'shutdown') { 
 socket_close($msgsock); 
 break 2; 
 } 
 if ($buf == 'sun') { 
 echo'what are you doing?'; 
 } 
 $talkback = "Backinformation : '$buf'.\n"; 
 socket_write($msgsock, $talkback, strlen($talkback)); 
 echo "$buf\n"; 
 } while (true); 
 
 socket_close($msgsock); 
 
} while (true); 
 
socket_close($sock); 
?> 

二、client.php客户端:

<?php 
error_reporting(E_ALL); 
//端口111 
$service_port = 111; 
//本地 
$address = 'localhost'; 
//创建 TCP/IP socket 
$socket = socket_create(AF_INET, SOCK_STREAM, SOL_TCP); 
if ($socket < 0) { 
 echo "socket创建失败原因: " . socket_strerror($socket) . "\n"; 
} else { 
 echo "OK，HE HE.\n"; 
} 
$result = socket_connect($socket, $address, $service_port); 
if ($result < 0) { 
 echo "SOCKET连接失败原因: ($result) " . socket_strerror($result) . "\n"; 
} else { 
 echo "OK.\n"; 
} 
//发送命令 
$in = "HEAD / HTTP/1.1\r\n"; 
$in .= "Connection: Close\r\n\r\n"; 
$out = ''; 
echo "Send Command.........."; 
$in = "sun\n"; 
socket_write($socket, $in, strlen($in)); 
echo "OK.\n"; 
echo "Reading Backinformatin:\n\n"; 
while ($out = socket_read($socket, 2048)) { 
 echo $out; 
} 
echo "Close socket........"; 
socket_close($socket); 
echo "OK,He He.\n\n"; 
?> 

这两段代码是简单介绍用PHP实现客户端和服务端的通信

具体操作,在DOS下用PHP命令打开SERVER,处于监听状态..

再打开一个DOS窗口,用PHP命令打开CLIENT,会得到服务端的回应....
