Solved How to foreach() every single world in the server?

Can anyone tell me the proper way to foreach() every single world in the server to do different things? Because getLevels() from the server class will return a Level instance and not an array of every levels in the server.

 

PHP:

foreach (array_map(function (Level $level) {
    return $level->getName();
}, $this->getServer()->getLevels()) as $levelName) {
            
}
