Array push doesn't work

Hello. I have there code.
When player touch sign:

PHP:

if($x == 257 && $y == 63 && $y == 275){
     $e->setCancelled();
     $this->joinArena($p, "Pizza", $arX, $arY, $arZ);
   }


And

PHP:

public function joinArena(Player $player, $arena, $x,$y, $z){
  array_push($this->players[$arena], $player->getName());
  $player->teleport(new Position($x, $y, $z, $this->getServer()->getLevelByName($arena)));
}


But when I touch, nothink happens.

 

How is this relevant to array_push? What are $x, $y, $z, $arX, $arY, $arZ, $p, etc.? Do you get any errors? Is joinArena() being called correctly?

 

Yes, this function is correctly maked. I tried same without function (array_push in PlayerInteractEvent), but it didn't added player to array.
No, there aren't any errors in console

 

$arX, $arY and $arZ are coordinates of arena.

 

This is equivalent to array_push().

PHP:

$this->players[$arena] = $player->getName();

 

array_push wouldn't cause nothing to happen. Try debugging to see if joinArena is being called. Something like this would work:

PHP:

 //Assuming your class extends PluginBase:
$this->getLogger()->notice("joinArena run"); 

I still know absolutely nothing about what $p, $x, $y, or $z are, or how your listener is set up.

 

And also its recommended to use that method instead of array_push(), due to it not being a function.
