spam kick

Can someone show me an example on how to kick a player if the amount of messages is 2 in 1 second?

Use ChatDefender -.-
It not kick players, it block spammer messages.

I think its either my server or api 1.12.0 doesn't support it, but it doesn't work for me.

But could this work?

PHP:

public function onChat(PlayerChatEvent $event){
$p = $event->getPlayer();
  If($event->getMessage() === 2){
   $p->kick();
   return true;
}
}

Of course no... $event->getMessage() only returns the message.

PHP:

private $last=[];
public function onChat(PlayerChatEvent $e){
  $player=$event->getPlayer();
  $playerId=$player->getId(); // an identifier just for that player
  if(isset($this->last[$playerId]) and
    microtime(true)-$this->last[$playerId] < 0.5){ // if this is not the first message the player chatted, and the last message was sent less than 0.5 second ago
    $event->setCancelled();
    $player->kick();
    return;
  }
  $this->last[$playerId]=microtime(true); // save the current time as the time the player last chatted
}

Remember to unset the data when the player quits, or the memory will accumulate and overload.

In microtime(true)-... It marks syntax error

And what exactly is that syntax error?
