Get a random username

I don't understand whats wrong with my code (old API)!

PHP:

$pList = $this->api->player->getAll();
$rNumPlayer = rand(0, count($pList) - 1);
$rPlayer = $pList[$rNumPlayer];
$rPlayerName = $rPlayer->username;


When broadcasting a message using that $rPlayerName nothing appears!

Use foreach(?) i'm not sure

How would I make that with a foreach?

is rPlayerName a variable

You are not using Java. $pList is ordered by client IDs ($ip . ":" . $port), not with increasing integers. Therefore, your randomly generated integer is not an existent offset in $pList.

Use array_rand().
