Run function in background

I think the problem is that the function in the main class don't waits for the end of the AsyncTask. How can I return it if the AsyncTask is done?
Otherwise the variable is always empty

 

I have this in my AsyncTask. There I can echo the result. But I want to display it on command (using a function)

 

I don't really understand... Can u give me an example? Or is there a better way to get the status of another server?

 

But how can I get the result of onComplete in the main task?? I want to get the result of the starter task (getStatus() in the main)

 

PHP:

private $ip, $port, $timeout, $server, $status;
public function __construct(Server $server, $ip, $port, $timeout = 10){
    $this->ip = $ip;
    $this->port = $port;
    $this->timeout = $timeout;
    $this->server = $server;
}

public function onRun(){
    $minecraft = @fsockopen($this->ip, $this->port, $this->timeout);
    $this->status = $minecraft == true ? "online" : "offline";
}

public function onCompletion(Server $server){
    $server->getLogger()->notice("
        Background task has finished. The output was:
    ".$this->status);
    $server->getPluginManager()->getPlugin("pluginName")->result = $this->status;
}


 

No. I already tried that. And it doesn't work because when I run the command, the variable is empty. And if I do /info list, I see more than one server

 

That's in my AsyncTask ...

PHP:

public function onCompletion(Server $server){
    $server->getLogger()->notice("
        Background task has finished. The output was:
    ".$this->status);
    $server->getPluginManager()->getPlugin("MyPlugin")->onComplete() = $this->status;
}


It works. But I don't get it in the main task. I could add onComplete($status). But I want to return it in the main task :/

 

How does that even work?! You set a function equal to a variable!

 

I think u really understand what I want to do.

1. I start the AsyncTask in a function (getStatus(){}) in the main Class.
2. The AsyncTask works correctly and gives the right result onCompletion(){}
3. In the getStatus() task I want to get the result of the startet AsyncTask (doesn't work). I start the AsyncTask using this:

PHP:

$status = $this->getServer()->getScheduler()->scheduleAsyncTask(new StatusTask($ip, $port, $timeout));

//Now I want to return $this->getResult () from the task in this function

 

PHP:

$status = $this->getServer()->getScheduler()->scheduleAsyncTask($task = new StatusTask($ip, $port, $timeout)); // status is null
$result = $task->getResult();

 

This gives me nothing. And no error

 

I don't think you should do something as complex as this. Threading/Async stuff is quite advanced and you don't seem to understand it.
You just need to pass your stuff back into your plugin class. If you need an example, you may want to look at this

I got it to a class in the main class. But how can I display it now on Command?

PHP:

public function asyncTaskCallBack($data) {
echo $data;
}

 

It's not only on command. I run the function to get the status on command and to refresh status signs. How would u do that?
