Solved Array_push replace old value

Hello
I'm having little problem with my code xD
And it's when I try add new player in array it replaces old one, so know someone how can help me?
This is array for all games:

PHP:

public $games = array();

And this is how I add the player in array:

PHP:

public function addPlayer(Player $player, $game){
    $this->games[$game] = array();
    array_push($this->games[$game], $player);   
    }

//$this->addPlayer($player, $game); in other functions
    

So it adds fine the first player but when i try to add the second player it replaces the first
And also made a var_dump (var_dump($this->games[$game]) and here is:

Spoiler: First var_dump

array(1) {
[0]=>
object(pocketmine\Player)#11053 (0) {
}
}

Spoiler: Second var_dump

array(1) {
[0]=>
object(pocketmine\Player)#17836 (0) {
}
}

 

PHP:

$this->games[$game][] = $player;

 

Yes I tried this too but still replace old one

 

Ups you are right just I forgot to delete $this->games[$game] = array(); xD
Thanks @Sandertv !

 

No problem.

 

$this->games[$game] is not an array? QAQ
