Solved Get the nearest player on the spawn

Hey! I wanna make the following plugin:
The nearest player, they are in the near of the spawn, get a message like "You are in the near of the spawn!".
Does anyone know how can I make this plugin? Thanks!

PHP:

$distance = PHP_INT_MAX;
$player = null;
$lvl = $this->getServer()->getLevelByName("world");
foreach($lvl->getPlayers() as $pl){
  if($pl->distanceSquared($lvl->getSafeSpawn()) < $distance){
    $distance = $pl->distanceSquared($lvl->getSafeSpawn());
    $player = $pl;
  }
}

if($player != null){
  $player->sendMessage("Hi");
}

Thank you!! I will try it out! :3

How much difference is this from a direct plugin request :/
