創建tcp服務器
1 關閉服務器防火墻（或者允許tcp連接） 注意放行端口
2 開啟服務
$service = new swoole_server("0.0.0.0",9501);
$service->set([
'worker_num'=>1,
'max_request'=>10000,
]);
$service->on('connect',function ($service,$fd,$reactor_id){
echo "Welcome to 四川 $service --- $reactor_id --- $fd \n" ;
});
$service->on('receive',function ($service,$fd,$reactor_id,$data){
$service->send("$service say: $fd from $reactor_id you send $data \n");
});
$service->on('close',function ($service,$fd){
echo "$fd 離開 $service 關閉";
});
$service->start();
