How Do I Fix This?

Hi guys I made a plugin but my server wont output what I want I made a variable $username = $issuer-> username; and in the console it says undefined variable: issuer here is my plugin code

PHP:

<?php

/*
__PocketMine Plugin__
name=IDisconneted
description=Plugin created with PMMPPG by SuperChipsLP
version=1.0
author=PluginMastered
class=Disconnect
apiversion=10
*/

    class Disconnect implements plugin{

    private $api;

    public function __construct(ServerAPI $api, $server = false){

        $this->api = $api;

    }

    public function init(){

    $this->api->addHandler("player.quit", array($this, "eventHandler"), 100);

    $username = $issuer-> username;

    }
   
    public function eventHandler($data, $event)
    {
    switch($event)
    {
        case 'player.quit':

            $this->api->chat->broadcast("$username Has Left The Game");

        break;
    }

    }

    public function __destruct(){

    }

}


The variable $username is out of scope...
You need to declare it in the eventHandler function:

Also you need to get the issuer like this:

PHP:

<?php

/*
__PocketMine Plugin__
name=IDisconneted
description=Plugin created with PMMPPG by SuperChipsLP
version=1.0
author=PluginMastered
class=Disconnect
apiversion=10
*/

    class Disconnect implements plugin{

    private $api;

    public function __construct(ServerAPI $api, $server = false){

        $this->api = $api;

    }

    public function init(){

    $this->api->addHandler("player.quit", array($this, "eventHandler"), 100);

    }
  
    public function eventHandler($data, $event)
    {
    switch($event)
    {
        case 'player.quit':
            $issuer = $data['player'];
            $username = $issuer-> username;
            $this->api->chat->broadcast("$username Has Left The Game");

        break;
    }

    }

    public function __destruct(){

    }

}
