PDO MySQL prepared INSERT syntax error

Have seen tons of similar questions but still can't find out what's going on.

I'm using PHP's PDO to prepare a statement like that:

try{
    $statement = $db->prepare("INSERT INTO $date (name, surname, email, phone, comment) VALUES (:name, :surname, :email, :phone, :comment)");
    $statement->bindParam(':name', $name);
    $statement->bindParam(':surname', $surname);
    $statement->bindParam(':email', $email);
    $statement->bindParam(':phone', $phone);
    $statement->bindParam(':comment', $comment);

    $statement->execute();
}
catch(PDOException $e){
    die("Connection to database failed: " . $e->getMessage());
}

Have tried escaping everything with [] and specifying the database name before table name, but keep getting
