Editer le profile

Bonjour, je n'arrive pas à modifier le profil où on se connecte. Par exemple lorsque je me connecte avec un compte A, et je me dirige vers modifier le profile, il affiche les donées du compte B/ de l'user le plus récent

Voici le code pour créer, se connecter, modifier un utilisateur model.php :

<?php 
    class model{

        private $server = "localhost";
        private $username = "root";
        private $password = "";
        private $db = "formation_db";
        private $conn;

        public function __construct()
        { 
            try {
                $this->conn = new mysqli(
                                $this->server, 
                                $this->username, 
                                $this->password,
                                $this->db 
                            );
        }   catch(Exception $e) 
        {
            echo "Erreur de connexion" . $e->getMessage();
        }
    }
function connexionUser(){
    session_start();
    if(isset($_POST['email']) && isset($_POST['userPassword'])) {
        $email = $_POST['email'];
        $userPassword = $_POST['userPassword'];

        if(empty($email)){
            header("Location: index.php?error=Email requis");
            exit();
        } else if(empty($userPassword)) {
            header("Location: index.php?error=Mot de passe requis");
