PHP+swoole实现简单多人在线聊天群发效果
下面本篇文章主要给大家介绍一下PHP+swoole如何实现简单多人在线聊天群发，有一定的参考价值，有需要的朋友可以参考一下，希望对你有所帮助。
由于本文的能力有限，有好多聊天逻辑的细节没有实现，只实现了群发，具体代码如下所示：
php代码：
$serv = new swoole_websocket_server("127.0.0.1",3999);
//服务的基本设置
$serv->set(array(
'worker_num' => 2,
'reactor_num'=>8,
'task_worker_num'=>1,
'dispatch_mode' => 2,
'debug_mode'=> 1,
'daemonize' => true,
'log_file' => __DIR__.'/log/webs_swoole.log',
'heartbeat_check_interval' => 60,
'heartbeat_idle_time' => 600,
));
$serv->on('connect', function ($serv,$fd){
// echo "client:$fd Connect.".PHP_EOL;
});
//测试receive
$serv->on("receive",function(swoole_server $serv,$fd,$from_id,$data){
// echo "receive#{$from_id}: receive $data ".PHP_EOL;
});
$serv->on('open', function($server, $req) {
// echo "server#{$server->worker_pid}: handshake success with fd#{$req->fd}".PHP_EOL;;
// echo PHP_EOL;
});
$serv->on('message',function($server,$frame) {
// echo "message: ".$frame->data.PHP_EOL;
$msg=json_decode($frame->data,true);
switch ($msg['type']){
case 'login':
$server->push($frame->fd,"欢迎欢迎~");
break;
default:
break;
}
$msg['fd']=$frame->fd;
$server->task($msg);
});
$serv->on("workerstart",function($server,$workerid){
// echo "workerstart: ".$workerid.PHP_EOL;
// echo PHP_EOL;
});
$serv->on("task","on_task");
$serv->on("finish",function($serv,$task_id,$data){
return ;
});
$serv->on('close', function($server,$fd,$from_id) {
// echo "connection close: ".$fd.PHP_EOL;
// echo PHP_EOL;
});
$serv->start();
function on_task($serv,$task_id,$from_id,$data) {
switch ($data['type']){
case 'login':
$send_msg="说:我来了~";
break;
default:
$send_msg="说:{$data['msg']['speak']}";
break;
}
foreach ($serv->connections as $conn){
if ($conn!=$data['fd']){
if (strpos($data['msg']['name'],"游客")===0){
$name=$data['msg']['name']."_".$data['fd'];
}else{
$name=$data['msg']['name'];
}
}else{
$name="我";
}
$serv->push($conn,$name.$send_msg);
}
return;
}
function on_finish($serv,$task_id,$data){
return true;

Explain JSON Web Tokens (JWT) and their use case in PHP APIs.
Apr 05, 2025 am 12:04 AM
JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1.

When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,
