Best way to check sign text?

I was wondering what the best way was to check the text on a sign (I'm pretty sure there's multiple ways ) as I want as few lines of code as possible. I'm currently using this :

PHP:

public function onInteract(PlayerInteractEvent $event) {
        $signtext = $event->getPlayer()->getLevel()->getTile($this->main->getBlock())->getText();
       
        if($event->getBlock()->getId() == 68) {
            if($signtext[0] == "-join-") {
                if($signtext[1] == "small") {
                    $event->getPlayer()->teleport(new Vector3(141, 11, 33));
                }
                elseif($signtext[1] == "medium") {
                    $event->getPlayer()->teleport(new Vector3(184, 11, 28));
                }
                elseif($signtext[1] == "large") {
                    $event->getPlayer()->teleport(new Vector3(131, 11, -18));
                }
                elseif($signtext[1] == "skyisland") {
                    $event->getPlayer()->teleport(new Vector3(207, 27, 4));
                }
                elseif($signtext[1] == "wasteland") {
                    $event->getPlayer()->teleport(new Vector3(-4, 7, 106));
                }
                elseif($signtext[1] == "end") {
                    $event->getPlayer()->teleport(new Vector3(-62, 8, 165));
                }
                elseif($signtext[1] == "village") {
                    $event->getPlayer()->teleport(new Vector3(-120, 5, 164));
                }
                elseif($signtext[1] == "nether") {
                    $event->getPlayer()->teleport(new Vector3(-68, 13, 103));
                }
            }
        }
    }
 

Thanks

PHP:

use pocketmine\tile\Sign;
use pocketmine\tile\Tile;
    
       if($event->getBlock()->getID() == 323 || $event->getBlock()->getID() == 63 || $event->getBlock()->getID() == 68)
       {
         $sign = $event->getPlayer()->getLevel()->getTile($event->getBlock());
        
         if(!($sign instanceof Sign))
         {
           return;
         }
      }

He asked for checking Sign Text, not just a sign.

yes... but checking is after

PHP:

  if(!($sign instanceof Sign)) { return; }

there u can check the lines

PHP:

        $sign = $sign->getText();
         $i = $sign[1];
         $i2 = $sign[2];
         $i3 = $sign[3];

You forgot $sign[0]

-.- i didnt xD

PHP:

    public function tileupdate(SignChangeEvent $event)
    {

            if($event->getBlock()->getID() == 323 || $event->getBlock()->getID() == 63 || $event->getBlock()->getID() == 68)
            {
                $sign = $event->getPlayer()->getLevel()->getTile($event->getBlock());
                  
                if(!($sign instanceof Sign))
                {
                    return true;
                }
                $sign = $event->getLines();
                  
                if($sign[0]=='[Bettkampf]')
                {
                    if(!$event->getPlayer()->isOp())
                    {
                        $event->setLine(0,"[Nichtig]");
                        return false;
                    }
                }
            }
            return true;
      
    }

I would use switch and case like so

PHP:

$lines= $sign->getText();
$ln1 = $lines[0];
switch($ln1) {
case "Word":

break;
case "DiffWord":

break;
}

of course you can change it to do any line on the sign you may like

I am using this code:

PHP:

public function playerBlockTouch(PlayerInteractEvent $event){
  if($event->getBlock()->getID() == 323 || $event->getBlock()->getID() == 63 || $event->getBlock()->getID() == 68){
  $sign = $event->getPlayer()->getLevel()->getTile($event->getBlock());
  if(!($sign instanceof Sign)){
  return;
  }
  $sign = $sign->getText();
  $this->getServer()->loadLevel("PVP");
  if($sign[0]=='[PVP]'){
  if(Server::getInstance()->loadLevel("PVP") != false){
  $event->getPlayer()->sendMessage("[server] teleporting you to arena...");
  $event->getPlayer()->teleport(new Position($x, $y, $z, $this->getServer()->getLevelByName("PVP")));
}
}


Works perfectly for me.

Thanks for all your input

I found this code works fastest

PHP:

public function onInteract(PlayerInteractEvent $event) {
        $sign = $event->getPlayer()->getLevel()->getTile($event->getBlock());
        if($event->getBlock()->getId() == 323 || $event->getBlock()->getId() == 63 || $event->getBlock()->getId() == 68) {
            if($sign instanceof Sign) {
                $signtext = $sign->getText();
                if($signtext[0] === "Tap to Join") {
                    if($signtext[1] === "Small PvP") {
                        $event->getPlayer()->teleport(new Vector3(141, 11, 33));
                        $event->getPlayer()->sendMessage("Teleporting you to Small PvP.");
                    }
                    elseif($signtext[1] === "Medium PvP") {
                        $event->getPlayer()->teleport(new Vector3(184, 11, 28));
                        $event->getPlayer()->sendMessage("Teleported you to Medium PvP.");
                    }
                    elseif($signtext[1] === "Large PvP") {
                        $event->getPlayer()->teleport(new Vector3(139, 11, -18));
                        $event->getPlayer()->sendMessage("Teleported you to Large PvP.");
                    }
                    elseif($signtext[1] === "Sky Land") {
                        $event->getPlayer()->teleport(new Vector3(107, 27, 4));
                        $event->getPlayer()->sendMessage("Teleported you to Sky Islands PvP.");
                    }
                    elseif($signtext[1] === "Nether PvP") {
                        $event->getPlayer()->teleport(new Vector3(-68, 13, 103));
                        $event->getPlayer()->sendMessage("Teleported you to Nether PvP.");
                    }
                    elseif($signtext[1] === "End PvP") {
                        $event->getPlayer()->teleport(new Vector3(-62, 8, 165));
                        $event->getPlayer()->sendMessage("Teleported you to End PvP.");
                    }
                    elseif($signtext[1] === "Wasteland PvP") {
                        $event->getPlayer()->teleport(new Vector3(-4, 7, 186));
                        $event->getPlayer()->sendMessage("Teleported you to Wasteland PvP.");
                    }
                    elseif($signtext[1] === "Small Village") {
                        $event->getPlayer()->teleport(new Vector3(-120, 5, 164));
                        $event->getPlayer()->sendMessage("Teleported you to Small Village PvP.");
                    }
                }
            }
        }
    }
