Solved How do I create a foreach for players?

Hello, I have a doubt, and state created a plugin, and for example, I want the command "test", give the player and others near the say within a radius of 5 blocks, give it an effect or enchantment, for this I understand that I need a foreach, but I do not know how to create it for this kind of thing, if someone can support me would be appreciated!!

 

PHP:

foreach(Server::getInstance()->getOnlinePlayers() as $player){
    if($player->distance($position) <= 5){
        // do your thing here
    }
}

 

Thank you very much, I would thank you very much for the answer, something else in the case of wanting to give an enchantment (in //do your thing here) as it would be?

 

PHP:

foreach(Server::getInstance()->getOnlinePlayers() as $player){
    if($player->distance($position) <= 5){
        $iteminhand = $player->getInventory()->getItemInHand();
        $en = Enchantment::getEnchantment(Enchantment::UNBREAKING);
        $ench = new EnchantmentInstance($en,10);
        $iteminhand->addEnchantment($ench);
        $player->getInventory->setItemInHand();
    }
}

 

Thank you very, very much to both who helped me, I will be able to continue with my plugin <3
