Get one random Player out of a List

Hey there.

How do I get a random Player out of a List? I'm saving Players into a YAML Config when doing a command. If there are 3 or more players in the list, one of them will be picked randomly and the player will get a sword.

I already done the List and the command, the only thing I need is the random pick.

PHP:

/** @var string[] $list */
$selected = [];
for($i = 0; $i < 3; $i++){
  while(in_array($k = mt_rand(0, count($list) - 1))); // using a while to avoid selecting duplications.
  $selected[] = $k;
}
$selections = array_map(function($k) use($list){
  return $list[$k];
}, $selected);


which sometimes return the same variable in different interval. its not that great. hoping to test @PEMapModder's method.

Hey, thanks for your Post but I still don't know how to do it :/
So, what I wanna do is:

PHP:

public function startGame(){
            $this->AStarted = true; // Sets the Game on true/started
           
           // Pick a random player out of $this->inA and teleport him to 0 0 0, teleport the other players to 1 1 1(Example)
        }

Then $this->inA is the $list. And for each $selected as $select, call teleport on $list[$select]

PHP:

public function startGame(){
$this->AStarted = true; // Sets the Game on true/started $list = $this->inA->getAll(); $selected = [];for($i = 0; $i < 3; $i++){ while(in_array($k = mt_rand(0, count($list) - 1))); // using a while to avoid selecting duplications.$selected[] = $k;}$selections = array_map(function($k) use($list){ return $list[$k];}, $selected);

foreach($selected as $select){
$list[$select]->teleport(...);
}
}

Is that correct?
Sorry but I don't code for that long and don't know much so yea.. But well thanks for your help!

Use my code to define things...
