Solved How do i get array key from a value?

i have a config db like this:

Code:

d4f6d43b-4989-3ab0-9d03-80694e247ebb:
  game_level: 22
  xp: 23565
  xp_left: 23629
  karma: 17144
  coins: 1915.000000
  xp_left_show: 64
  broken_blocks: 0
  language: english
  name: HerryYT
d4f6d43b-4989-3ab0-9d03-20694e2443bb:
  game_level: 22
  xp: 23565
  xp_left: 23629
  karma: 17144
  coins: 1915.000000
  xp_left_show: 64
  broken_blocks: 0
  language: english
  name: OtherUser

the first value is player uuid, how can i get the array by the name?
like i wanna add coins to this player, i  have only his name, how do i get coins from his name?

 

Oh i figured out myself...

Code:

        foreach($this->data->getAll() as $key => $data)
        {

            if ($data["name"] == $player->getName()){
                echo $data["coins"];
                var_dump($data);
            }
            /*if ( $data[$field] === $value )
                return $key;*/
        }
