GET method getting NULL [closed]

It was just your typo.

session_start();
    class Login
    {
    private $email;
    private $senha;
    private $db;

    public function __construct(PDO $db){
        $this->db = $db;
    }

    public function autenticar($email, $senha){
        $query = "select * from clientes where email='$email' and senha=$senha";
        echo $query."<br>";
        $stmt = $this->db->prepare($query);
        $stmt->execute();

        if(($stmt->fetch())){
            $_SESSION['logado'] = true;
            return true;
        }
        else{
            $_SESSION['logado'] = false;
            return false;
        }
    }
    }
    $email = htmlspecialchars($_GET['email']);
    $senha = htmlspecialchars($_GET['senha']);
    $db = new PDO("mysql:host=localhost;dbname=registroop","root","");
    $login = new Login($db);
    $resultado = $login->autenticar($email,$senha);




    if($resultado)
    echo "logado";
    else
    echo "não logado";

    echo "<br>";
