Solved get player on the player List

This my code
$pname->sendMessage("A"); not working. How to send message on the selected player (Drop Down Player List)

PHP:

public function gonderForm($player){
        $this->eco = EconomyAPI::getInstance();
        $list =[];
        foreach($this->getServer()->GetOnlinePlayers() as $p){
        $list[] = $p->getName();

     
        }
  $this->playerList[$player->getName()] = $list;
        $f =  $this->getServer()->getPluginManager()->getPlugin("FormAPI")->createCustomForm(function(Player $player, array $data = null){
            if($data === null){
                return true;
            }
            $index = $data[1];
            $pname = $this->playerList[$player->getName()][$index];

          
            if($this->eco->myMoney($player->getName()) >= $data[2]){
                $this->eco->reduceMoney($player, $data[2]);
                $this->eco->addMoney($pname, $data[2]);
                $pname->sendMessage("hesabına" .$data[2] ."TL para geldi" ); // THIS LINE
                $player->sendMessage("Hesabından" . $data[2] . "TL para kesildi");
            }else{
                $player->sendMessage("§8»§gGöndermek istediğin miktar kendi paranı aşıyor!");
            }
          

       });
       $f->setTitle("Para Gönderme Menüsü");
       $f->addLabel("§8»§fPara göndermek istediğin oyuncuyu seç");
       $f->addDropDown("", $this->playerList[$player->getName()]);
       $f->addInput("§8»§fGöndermek istediğin para miktarını gir", "Örn: 500");
    
       $f->sendToPlayer($player);
    }

 

Uh, array saves those player name not number

 

Turns

PHP:

  $pname = $this->playerList[$player->getName()][$index];

To

PHP:

  $pname = $this->playerList[$index];

 

Wait

 

If it doesn't work, changes

PHP:

  $index = $data[1];

to

PHP:

  $index = $data[0];
