In what ways can PHP and JavaScript work together effectively to achieve the desired outcome in a newsletter script?

To achieve the desired outcome in a newsletter script, PHP can handle server-side tasks such as storing subscriber information in a database, while JavaScript can be used for client-side interactions like form validation and dynamic content updates. By combining the strengths of both languages, we can create a seamless user experience and efficient data management in the newsletter script. 

<?php
// PHP code for storing subscriber information in a database
if($_SERVER["REQUEST_METHOD"] == "POST"){
    $email = $_POST['email'];
    
    // Connect to database
    $conn = new mysqli('localhost', 'username', 'password', 'newsletter_db');
    
    // Check connection
    if ($conn->connect_error) {
        die("Connection failed: " . $conn->connect_error);
    }
    
    // Insert subscriber information into database
    $sql = "INSERT INTO subscribers (email) VALUES ('$email')";
    
    if ($conn->query($sql) === TRUE) {
        echo "New subscriber added successfully";
    } else {
        echo "Error: " . $sql . "<br>" . $conn->error;
    }
    
    $conn->close();
}
?>
