服务器代码 tcp.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
$client = new swoole_client(SWOOLE_SOCK_TCP); | |
if(!$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; |
