服务器

<?php

// Server
// 设置错误处理
error_reporting(E_ALL);
// 设置运行时间
set_time_limit(0);
// 起用缓冲
ob_implicit_flush();
$ip = "127.0.0.1"; // IP地址
$port = 1000; // 端口号

$socket = socket_create(AF_INET, SOCK_STREAM, SOL_TCP); // 创建一个SOCKET
if ($socket)
echo "socket_create() successed!n";
else
echo "socket_create() failed:".socket_strerror($socket)."n";

$bind = socket_bind($socket, $ip, $port); // 绑定一个SOCKET
if ($bind)
echo "socket_bind() successed!n";
else
echo "socket_bind() failed:".socket_strerror($bind)."n";

$listen = socket_listen($socket); // 间听SOCKET
if ($listen)
echo "socket_listen() successed!n";
else
echo "socket_listen() failed:".socket_strerror($listen)."n";

while (true) {
$msg = socket_accept($socket); // 接受一个SOCKET
if (!$msg) {
echo "socket_accept() failed:".socket_strerror($msg)."n";
break;
}
$welcome = "Welcome to PHP Server!n";
socket_write($msg, $welcome, strlen($welcome));
while (true) {
$command = strtoupper(trim(socket_read($msg, 1024)));
if (!$command)
break;
switch ($command) {
case "HELLO":
$writer = "Hello Everybody!";
break;
case "QUIT":
$writer = "Bye-Bye";
break;
case "HELP":
$writer = "HELLOtQUITtHELP";
break;
default:
$writer = "Error Command!";
}
socket_write($msg, $writer, strlen($writer));
if ($command == "QUIT")
break;
}
socket_close($msg);
}
socket_close($socket); // 关闭SOCKET
?>

客户端

<?php

// Client
// 设置错误处理
error_reporting(E_ALL);
// 设置处理时间
set_time_limit(0);

$ip = "127.0.0.1"; // IP 地址
$port = 1000; // 端口号

$socket = socket_create(AF_INET, SOCK_STREAM, SOL_TCP); // 创建一个SOCKET
if ($socket)
echo "socket_create() successed!n";
else
echo "socket_create() failed:".socket_strerror($socket)."n";

$conn = socket_connect($socket, $ip, $port); // 建立SOCKET的连接
if ($conn)
echo "Success to connection![".$ip.":".$port."]n";
else
echo "socket_connect() failed:".socket_strerror($conn)."n";

echo socket_read($socket, 1024);

$stdin = fopen('php://stdin', 'r');
while (true) {
$command = trim(fgets($stdin, 1024));
socket_write($socket, $command, strlen($command));
$msg = trim(socket_read($socket, 1024));
echo $msg."n";
if ($msg == "Bye-Bye")
break;
}
fclose($stdin);
socket_close($socket);
?>
