get blocks around player

This method doesn't work. I am testing to get the block near the player.

PHP:

public function onPlayerMove(PlayerMoveEvent $e){
        $p = $e->getPlayer();
        foreach($p->getBlocksAround() as $b){
            if($b->getId() === 2){
                $p->sendMessage("TRUE");
            }
        }
    }

use var_dump() function to debug your code.
