Warn plugin

I'm stuck here
Code:

PHP:

        switch($command->getName())
        {
            case "warn":
            if(isset($args[2]))
            {
                if($this->getServer()->getPlayer($args[0]) instanceof Player)
                {
                    $PlayerName = $this->getServer()->getPlayer($args[0])->getName();
                    if($this->warnsys->get($PlayerName == true))
                    {
                        //Now what?
                    }
                    else
                    {
                        $reasonsArray = array($args[1] => $args[2]);
                        $this->warnsys->set($PlayerName, $reasonsArray);
                        $this->warnsys->save();
                    }
                    $tempMsgS = "Der Spieler '".$PlayerName."' wurde mit dem Grund '".$args[1]."' mit ".$args[2]." Punkten gewarnt! Er hat insgesamt "."TODO"." Punkte.";
                    $tempMsgToP = TF::RED."\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n DU WURDEST VON '".$sender->getName()."' MIT DEM GRUND '".$args[1]."' mit ".$args[2]." PUNKTEN GEWARNT! DU HAST "."TODO"." PUNKTE! MIT 10 PUNKTEN WIRST DU GEBANNT!";
                    $args[0]->getPlayer()->sendMessage($tempMsgToP);
                    $this->sendMsgToSender($sender, $tempMsgS);
                }
            }
            else
            {return false;}     
        return true;
        break;


Some additional explanation:
TF = TextFormat
sendMsgToSender is an function made by me (It does send an msg to the player or the console)
$this->warnsys is an instance of Config

Ok, this is plugin should do:
/warn <PlayerName> <Reason> <Warning-Points>
It already can save that for ONE TIME
But then the next time what should i do that i can have unlimited Reason-Points arrays per player?
(//Now what?) in the code

Before everything else, if($args[0]->getPlayer() instanceof Player) wtf is this?

$this->getServer()->getPlayer($args[0])

$this->warnsys->get($PlayerName == true)

I suppose you misplaced == true?
Also, == true is as good as nothing. You can omit that.

Now, would you mind telling us what $this->warnsys is about?

Read my post please

Yes, I saw. But you didn't explain the structure in your Config.

The structure is only written by the code above

Ok, it appears no one is understanding what i want to code and what my code does...
What I want to code:
Player executes /warn Player7373 Do_not_grief! 1
and /warn Player7373 Do_not_grief_again! 3
The warnsys.yml should now look like this:

PHP:

Player7373:
  "Do_not_grief!":
  - 1
  "Do_not_grief_again!":
  - 3


The code I have written so far is only able to store one reason and point pack per player
(For the code look above)
For more info please read the initial post again!

I need to so sth with Config::setNested()

No one wants to help me?

Bumping thread.

Explain what this line is supposed to do?

PHP:

if($this->warnsys->get($PlayerName == true))

Now, I would just do it like this. I won't even make an if-else.

PHP:

$array = $this->warnsys->get($playerName, []); // return an empty array if the player has no previous warnings
$array[$args[1]] = $args[2];
$this->warnsys->set($playerName, $array);

Thanks!
I have to learn so much...
Will recode that tomorrow
