服务器代码 tcp.php
<?php
//创建Server对象,监听 127.0.0.1:9501 端口
$server = new swoole_server('127.0.0.1', 9501);
$server->set([
'worker_num' => 4
]);
//监听连接进入事件
$server->on('Connect', function ($server, $fd) {
echo "Client: Connect.\n";
});
//监听数据接收事件
$server->on('Receive', function ($server, $fd, $reactor_id, $data) {
$server->send(1, "Server:$fd- {$data}");
});
//监听连接关闭事件
$server->on('Close', function ($server, $fd) {
echo "Client: Close.\n";
});
//启动服务器
$server->start();
客户端代码 tcp_client.php
<?php
$client = new swoole_client(SWOOLE_SOCK_TCP);
if(!$client->connect("127.0.0.1", 9501)) {
echo "链接失败";
}
//php内置cli常量
fwrite(STDOUT, "请输入消息:");
$msg = trim(fgets(STDIN));
//发送消息给tcp server服务器
$client->send($msg);
//接受来自server的消息
$result = $client->recv();
echo $result;
客户端和服务器运行
