I get an error with a plugin

How to teleport to an other world? I used this code but it did not work:

PHP:

    public function onInteract(PlayerInteractEvent $this, $event){
        $player = $event->getPlayer();
        $name = $player->getName();
        $item = $player->getInventory()->getItemInHand();
        $itemid = $item->getID();
        $block = $event->getBlock();
        $level = $this->owner->getServer()->getLevelByName("$lvname");


        if($item->getName() == C::BOLD.C::GREEN."Teleporter"){
            $this->TeleportItems($player);
        }

        elseif ($item->getName() == C::BOLD . C::GREEN . "KitPvP"){
            $this->MainItems($player);
            $lvname = KitPvP;
            $player->teleport($level->getSafeSpawn());
       }

I get this error:

Code:

[11:38:01] [CRITICAL]: ParseError: "syntax error, unexpected '$this' (T_VARIABLE)" (EXCEPTION) in "/plugins/Core_v0.0.1.phar/src/Core/Main" at line 123

Line 123:

PHP:

        $level = $this->owner->getServer()->getLevelByName("$lvname");

 

PHP:

public function onInteract(PlayerInteractEvent $event){
        $player = $event->getPlayer();
        $name = $player->getName();
        $item = $player->getInventory()->getItemInHand();
        $itemid = $item->getID();
        $block = $event->getBlock();
        $level = $this->owner->getServer()->getLevelByName("$lvname"); //what is $levname? Have you store any value?


 

PlayerInteractEvent $this, $event???
Please learn a bit of PHP. It should be:

PHP:

public function onInteract(PlayerInteractEvent $event) { }

$this is a reserved variable in PHP, and can not be re-assigned, because it refers to the current object.

 

Ok...

 

Same result. And yes I have stored:

PHP:

        elseif ($item->getName() == C::BOLD . C::GREEN . "KitPvP"){
            $this->MainItems($player);
            $lvname = KitPvP;
            $player->teleport($level->getSafeSpawn());
       }

 

Show your code now please.

Who moved it to Facepalm?

 

$lvname is clearly undefined. What should it be?

 

It should be the level name I want to tp.

 

My problem is not $lvname yet. My problem is $this in line 123:
$level = $this->owner->getServer()->getLevelByName("$lvname");

 

You defined $lvname below that line
All code run line by line

 

So that's why this was moved to facepalm.
Can't help you much further if you don't at least know the basic syntax of PHP.
