Solved Unset a key from yaml

I've been trying to remove a key from my config!
Example:

I want to remove "Mojang" from this config:

PHP:

Microsoft:
    Mojang:
        Bugs: 1230
        Employees: 69
    Minecraft:
        Bugs: 200000
        Ceo: minijaham


My previous attempt:

PHP:

foreach ($data->get("Microsoft") as $val => $key) {
    $name = array_search($val, $data->get("Microsoft"));
    var_dump($name); // Outputs Mojang and Minecraft (string)
    unset($data->get("Microsoft")[$name]); // bool(false) ???? wtf
}
$data->save();


I know I'm doing something incorrectly, as I've done this before.
But I can't quite figure out what I am doing wrong!

 

try

PHP:

$all = $data->get("Microsoft");
unset($all["Mojang"]);
$data->set("Microsoft", $all);
$data->save();


 

Now that I think about it, I think I forgot to set the unsetted values.
I feel so dumb! I'll try it and come back with a result Thank you!

 

Result:

Worked!
Thank you so much @HeyDeniis_
