Solved PlayerInteractEvent

Hello, I would like to add in the code of my server a way of execution of code, for example, with a arrow named "test", one click on a block of emerald and its execute a code (of course all this is is an example), the code I find does not work What for?

PHP:

public function onInteract(PlayerInteractEvent $event){
    $player = $event->getPlayer();
    $item = $event->getItem();
    $block = $event->getBlock();

    if($item->getId() == yourid){

        if($block->getId() == yourblock){

            $player->sendMessage("Hello world");
        }
    }
}

 

PHP:

public function onInteract(PlayerInteractEvent $event){
$player = $event->getPlayer();
$item = $player->getInventory()->getItemInHand();
$block = $event->getBlock();
if($block->getId() === 1){
if($item->getId() === 276){
//TODO


 

PHP:

use pocketmine\block\Block;
use pocketmine\event\player\PlayerInteractEvent;
use pocketmine\item\Item;

    public function onInteract(PlayerInteractEvent $event){
        $player = $event->getPlayer();
        $item = $player->getInventory()->getItemInHand();
        $block = $event->getBlock();
        if($block->getId() === Block::EMERALD_BLOCK && $item->getId() === Item::ARROW && $item->getName() === "test"){
            //code
        }
    }
