How to load autoload.php in PMMP?

I want to load autoload.php in PMMP.
So, I used require, require_once and include functions.
But, PMMP stoped if used those functions.

How to fix this problem?

code is...

PHP:

<?php
namespace EasyCHAT;

use pocketmine\Player;
use pocketmine\plugin\PluginBase;
use pocketmine\Server;
use pocketmine\event\Listener;
use pocketmine\event\player\PlayerChatEvent;
use pocketmine\utils\Config;
use EasyCHAT\Chat;
use Ratchet\MessageComponentInterface;
use Ratchet\ConnectionInterface;
use Ratchet\Server\IoServer;
use Ratchet\WebSocket\WsServer;
use Ratchet\Http\HttpServer;

require __DIR__.'/vendor/autoload.php';

class EasyCHAT extends PluginBase implements Listener{
//....

 

Sorry.
This is solved problem.

 

and I made new thread.
