How can PHP and MySQL be effectively used to manage newsletter subscriptions and distribution?

To manage newsletter subscriptions and distribution using PHP and MySQL, you can create a database table to store subscriber information and use PHP to handle subscription requests and distribution of newsletters. You can insert new subscribers into the database, update subscription preferences, and send newsletters to all subscribers in the database. 

// Connect to MySQL database
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "newsletter";

$conn = new mysqli($servername, $username, $password, $dbname);

// Check connection
if ($conn->connect_error) {
    die("Connection failed: " . $conn->connect_error);
}

// Subscribe a new user
$email = $_POST['email'];
$sql = "INSERT INTO subscribers (email) VALUES ('$email')";
$conn->query($sql);

// Update subscription preferences
$email = $_POST['email'];
$preferences = $_POST['preferences'];
$sql = "UPDATE subscribers SET preferences='$preferences' WHERE email='$email'";
$conn->query($sql);

// Send newsletter to all subscribers
$subject = "Newsletter";
$message = "This is a newsletter message.";
$sql = "SELECT email FROM subscribers";
$result = $conn->query($sql);

while($row = $result->fetch_assoc()) {
    $to = $row['email'];
    mail($to, $subject, $message);
}

// Close database connection
$conn->close();
