How to write configs?

PHP:

public function onLoad(){
        @mkdir($this->getDataFolder());
        $this->SpleefOne = (new Config($this->getDataFolder()."SpleefOne.yml", Config::YAML, array(
            "Join-Spleef-One-Message" => TextFormat::RED."[Spleef]".TextFormat::YELLOW."Joining Spleef Lobby One!",
            "Spleef_One_Players" => 0,
            "Spleef_One_In_Progress" => false,
            "SpleefOnePlayerOne" => null,
            "SpleefOnePlayerTwo" => null,
            "SpleefOnePlayerThree" => null,
            "SpleefOnePlayerFour" => null,
            "SpleefOnePlayerFive" => null,
            "SpleefOnePlayerSix" => null,
            "SpleefOnePlayerSeven" => null,
            "SpleefOnePlayerEight" => null,
            "max-players" => 8,
            )));
        $this->getLogger()->info(TextFormat::BLUE."CloudPvP Spleef");

    }


(YAML)

Code:

---
Join-Spleef-One-Message: §c[Spleef]§eJoining Spleef Lobby One!
Spleef_One_Players: 0
Spleef_One_In_Progress: false
SpleefOnePlayerOne: ~
SpleefOnePlayerTwo: ~
SpleefOnePlayerThree: ~
SpleefOnePlayerFour: ~
SpleefOnePlayerFive: ~
SpleefOnePlayerSix: ~
SpleefOnePlayerSeven: ~
SpleefOnePlayerEight: ~
max-players: 8
...

PHP:

        public function onPlayerInteract(PlayerInteractEvent $event){
            $p = $event->getPlayer();
           
            $tile = $event->getBlock()->getLevel()->getTile($event->getBlock());
            if ($tile instanceof Sign) {
                $tiles = $tile->getText();
                 if ($tiles[0] == "[CloudPvP]" and $tiles[1] == "Spleef"){
                     $tile->setText($tiles[0], $tiles[1], $this->SpleefOne->get("Spleef_One_In_Progress"), $this->SpleefOne->get("Spleef_One_Players"). "/" . $this->SpleefOne->get("max-players"));
                     if ($this->SpleefOne->get("Spleef_One_In_Progress") == false and $this->SpleefOne->get("Spleef_One_Players") < 8){
                       
                          $p->sendMessage($this->SpleefOne->get("Join-Spleef-One-Message"));
                          $this->SpleefOne->get("Spleef_One_Players");
                          $this->SpleefOne->get("Spleef_One_In_Progress") == false and $this->SpleefOne->get("Spleef_One_Players")+1;
                               
                                if ($this->SpleefOne->get("SpleefOnePlayerOne") == null or $this->SpleefOne->get("SpleefOnePlayerOne")->isOnline() == false) {
                                 $event->getPlayer()->teleport(new Vector3(-1206, 26, 280));
                                 $p->sendMessage(TextFormat::RED."[Spleef] Please Wait.");
                                 $item = Item::get(256,0,1);
                                 $p->getInventory()->addItem($item);
               
                                 $this->SpleefOne->get("SpleefOnePlayerOne") = $this->p->getName();
                                
                                    
                                    
                                
                               
                       
                                }
                      }
                 }
            }
        }

On the PHP code above, on the last line of text (which is obviously wrong and crashes the server) how do I correctly assign SpleefOnePlayerOne as $p's name in the config file?

Try

PHP:

$this->SpleefOne->set("SpleefOnePlayerOne", $p->getName());


well no crash but when i checked the config file (yes I did refresh) but SpleefOnePlayerOne was still set to null

Any help?

The question is, why use config?

Add this after setting the Player

PHP:

$this->SpleefOne->save();
