function publish() {
        global $client;
        echo "Mesage published\n";
        $client->disconnect();
}

function disconnect() {
        echo "Disconnected cleanly\n";
}

我尝试过：



我尝试将sub.php和pub.php放在路径/ var / www / html中并写入broswer



210.201 .4.111 / sub.php也写210.201.4.111/pub.php



但看不到任何数据

What I have tried:

I try put sub.php and pub.php in the path /var/www/html and write in broswer

210.201.4.111/sub.php also write 210.201.4.111/pub.php

but not see any data

推荐答案

client = new Mosquitto \Client（）;

client = new Mosquitto\Client();

client-> onConnect（' connect'）;

client->onConnect('connect');

client-> onDisconnect（' disconnect'）;

client->onDisconnect('disconnect');
