用PHP开发C/S结构（一个简单的例子）_PHP教程

服务器
// 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! ";
else
echo "socket_create() failed:".socket_strerror ($socket)." ";
$bind = socket_bind ($socket, $ip, $port); // 绑定一个SOCKET
if ($bind)
echo "socket_bind() successed! ";
else
echo "socket_bind() failed:".socket_strerror ($bind)." ";
$listen = socket_listen ($socket); // 间听SOCKET
if ($listen)

while (true)
