What is the best solution for sending newsletters using PHP and SQL tables?

To send newsletters using PHP and SQL tables, you can create a script that retrieves the subscriber emails from the database and sends the newsletter to each recipient using a loop. Make sure to sanitize the email content and handle any errors that may occur during the sending process. 

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

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

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

// Retrieve subscriber emails from the database
$sql = "SELECT email FROM subscribers";
$result = $conn->query($sql);

if ($result->num_rows > 0) {
    while($row = $result->fetch_assoc()) {
        $to = $row["email"];
        $subject = "Newsletter";
        $message = "This is your newsletter content";
        $headers = "From: your@email.com";

        // Send the newsletter
        if (mail($to, $subject, $message, $headers)) {
            echo "Newsletter sent to " . $to . "<br>";
        } else {
            echo "Failed to send newsletter to " . $to . "<br>";
        }
    }
} else {
    echo "No subscribers found";
}

$conn->close();
