swoole_server-getClientList

简介

用来遍历当前Server所有的客户端连接，Server::getClientList方法是基于共享内存的，不存在IOWait，遍历的速度很快。另外getClientList会返回所有TCP连接，而不仅仅是当前Worker进程的TCP连接。

实例代码

Server

<?php class Server {
     private $serv;public function __construct(){
     $this->serv = new swoole_server('127.0.0.1', 9501);//注意这里要用多进程模式，不填写默认是多进程$this->serv->set(array('worker_num' => 4,'daemonize' => false,'backlog' => 128,));$this -> query($this->serv);$this->serv->on('Connect', array($this,'onConnect'));$this->serv->on('Receive', array($this,'onReceive'));$this->serv->on('Close', array($this,'onClose'));$this->serv->start();}public function onConnect(swoole_server $server, int $fd, int $reactorId){
      print_r($fd."--连接上了\n"); }public function onReceive(swoole_server $server, int $fd, int $reactor_id, string $data){
     print_r("主进程\n");$start_fd = 0;while(true){$conn_list = $server->getClientList($start_fd, 10);if ($conn_list===false or count($conn_list) === 0){echo "finish\n";break;}$start_fd = end($conn_list);//返回数组的最后一个元素的值var_dump($conn_list);foreach($conn_list as $fd){$server->send($fd, "群发消息");}}}public function onClose(swoole_server $server, int $fd, int $reactorId){
     print_r($fd."--关闭了连接\n");}function query($server) {
     } }new Server();

Client

<?php $client = new swoole_client(SWOOLE_SOCK_TCP);
if (!$client->connect('127.0.0.1', 9501, -1))
{exit("connect failed. Error: {
    $client->errCode}\n");
}
$client->send("task");while (true) {$as = $client->recv();print_r($as."\n");
}

结果
