Whats wrong here?

Hi! I have been working on this plugin. I'm not sure whats wrong with it
My Loader:

PHP:

<?php

namespace RTG\ChatFilter;

/* Essentials */
use pocketmine\plugin\PluginBase;
use pocketmine\event\Listener;
use pocketmine\Player;
use pocketmine\Server;
use pocketmine\utils\Config;

/* Execution */
use pocketmine\command\CommandExecutor;

use RTG\ChatFilter\CMD\FilterCommand;

use pocketmine\event\player\PlayerChatEvent;

class Loader extends PluginBase implements Listener {
   
    public $whitelist;
   
    public function onEnable() {
        $this->getServer()->getPluginManager()->registerEvents($this, $this);
       
        /* For Commands */
        $this->getCommand("cf")->setExecutor(new FilterCommand ($this));
       
        /* CFG Setup */
       
        $this->whitelist = array();
       
        @mkdir ($this->getDataFolder());
        $list = new Config($this->getDataFolder() . "bannednames.txt", Config::ENUM);
        $this->whitelist = explode(", ", $list->getAll());
       
        $this->getLogger()->info("[LEET] ChatFilter has been enabled!");
    }
   
    public function onSave() {
        $list = new Config($this->getDataFolder() . "bannednames.txt", Config::ENUM);
        $list->setAll($this->whitelist);
        $list->save();
    }
       
        public function onChat(PlayerChatEvent $e) {
           
            $p = $e->getPlayer();
            $msg = $e->getMessage();
            $list = new Config($this->getDataFolder() . "bannednames.txt", Config::ENUM);
            $get = $list->getAll();
               
                if(strpos(strtolower($msg, $get) !== FALSE)) {
                    $p->sendMessage("[ChatFilter] Triggered!");
                    $e->setCancelled(true);
                }
               
        }
       
       
        public function getList() {
            return $this->whitelist;
        }

    public function onDisable() {
        $this->onSave();
    }
   
}

Any errors or crashes given?

 

None

 

It gives this

 

$config->getAll() already returns an array of every key => value in the config. explode() can only be used on strings, not arrays.

 

What about getAll(true)?

 

Why do you want to use explode?

 

I was trying to get that lines working with checking with the ChatEvent.

 

Then you might want to use
http://php.net/manual/en/function.implode.php

 

What you could do is: $data = file_get_contents($file)
Then $words = explode(",", $data);

 

I know about that

 

Ok, noted
