Save Block Location on Tap

Hi guys how can i save the location of the blocks to config.yml when i tap it

 

PHP:

public function onTap(PlayerInteractEvent $e){
  $p =  $e->getPlayer();
  $block = $e->getBlock();

  //i will use config you can use config or array
  //world
  $this->getConfig()->setNested("blocks.".$name.".world", $p->getLevel()->getName());
  //X
  $this->getConfig()->setNested("blocks.".$name.".x", $block->getX());
  //Y
  $this->getConfig()->setNested("blocks.".$name.".y", $block->getY());
  //Z
  $this->getConfig()->setNested("blocks.".$name.".z", $block->getZ());
  $this->getConfig()->save();
}
