How can I get All Players and put as array?

Code:

$all = $this->getServer()->getOnlinePlayers();

put that in $this->ex["Players"][] as array.

$this->ex["Players"][] = $all;

this doesn't work.

how can I?

 

Maybe you should use foreach.

Code:

foreach($this->getServer()->getOnlinePlayers() as $player){
  $this->ex['Players'] = $player->getName();
}

I don't know if it works.

 

That won't work, now you're setting a new name to the same key everytime. To achieve what you want you would need to use this

Code:

foreach($this->getServer()->getOnlinePlayers() as $player){
  $this->ex['Players'][] = $player->getName();
}

This will make an associative array like this:

Code:

<?php

$arr = ["Players" => ["player1", "player2", "player3"]];

?>
