下载安装完swoole，开启websocket服务器
php ws_server.php
服务端code
class WebSocketTest
{
public $server;
public function __construct()
{
$this->server = new Swoole\WebSocket\Server("0.0.0.0", 9501);
$this->server->on('open', function (Swoole\WebSocket\Server $server, $request) {
echo "server: handshake success with fd{
$request->fd}\n";
});
$this->server->on('message', function (Swoole\WebSocket\Server $server, $frame) {
echo "receive from {
$frame->fd}:{
$frame->data},opcode:{
$frame->opcode},fin:{
$frame->finish}\n";
foreach ($this->server->connections as $fd) {
$server->push($fd, $frame->data);
}
});
$this->server->on('close', function ($ser, $fd) {
echo "client {
$fd} closed\n";
});
$this->server->on('request', function ($request, $response) {
// 接收http请求从get获取message参数的值，给用户推送
// $this->server->connections 遍历所有websocket连接用户的fd，给所有用户推送
foreach ($this->server->connections as $fd) {
// 需要先判断是否是正确的websocket连接，否则有可能会push失败
if ($this->server->isEstablished($fd)) {
$this->server->push($fd, $request->get['message']);
}
}
});
$this->server->start();
}
}
new WebSocketTest();
