Why my AsyncTask doesn't work ?

Hi,
I am making an AsyncTask to do some MySQL stuff but it doesn't work.
Can someone help me ?
The connection works (to mysql).

PHP:

<?php

namespace misteboss\pvp\task\AsyncTask;

use pocketmine\scheduler\AsyncTask;
use pocketmine\Server;
use misteboss\pvp\Main;

class UpdateProfileTask extends AsyncTask{

public $bdd;
public $clientId;
public $adress;
public $date;
public $serveur;
public $device;
public $name;

    public function __construct($bdd, $clientId, $adress, $date, $serveur, $device, $name){
      $this->bdd = $bdd;
      $this->clientId = $clientId;
      $this->adress = $adress;
      $this->date = $date;
      $this->serveur = $serveur;
      $this->name = $name;
    }

    public function onRun(){
        $this->bdd = @mysqli_connect('127.0.0.1', 'root', 'password', 'GloriousFight', '3306');
        if(!$this->bdd)
        {
            echo "Unable to connect to MySQL";
         
            return;
        }
        mysqli_query($this->bdd, "UPDATE Joueurs SET UUID = $this->clientId WHERE IGN='$this->name'");
        mysqli_query($this->bdd, "UPDATE Joueurs SET LastIP = $this->adress WHERE IGN='$this->name'");
        mysqli_query($this->bdd, "UPDATE Joueurs SET LastJoin = $this->date WHERE IGN='$this->name'");
        mysqli_query($this->bdd,"UPDATE Joueurs SET Device = $this->device WHERE IGN='$this->name'");
        mysqli_query($this->bdd, "UPDATE Joueurs SET Serveur ='$this->serveur' WHERE IGN='$this->name'");
    }

}

Error :

Code:

Thanks for help

Can you give me an exemple of how to do it ? Without using libasynql librabry ?

 

I don't understand anything ;-;, there is no way to do it easily ?

 

The easiest thing to do would be to base the code for connecting to MySQL on the source of libasynql. Or just use libasynql for the plugin.

 

Code to copy ? What code are you talking about ?
