  • please try this code

    $sql = mysqli_query ($link,"UPDATE examinee SET user_name='".$user_name."', password='".$password."', date_of_registration='".$date_of_registration."' WHERE examinee_id = $examinee_id ");

    Explanation:you are using varchar datatype for stroing username, password, and date of registration in database. so the value should be in string format like 'username'.
