How can PHP code be optimized to efficiently retrieve and display data from a MySQL database for email generation?

To optimize PHP code for efficiently retrieving and displaying data from a MySQL database for email generation, you can use prepared statements to prevent SQL injection attacks and improve performance. Additionally, you can limit the number of columns fetched from the database to only those needed for the email generation process. 

// Establish a connection to the MySQL database
$pdo = new PDO("mysql:host=localhost;dbname=mydatabase", "username", "password");

// Prepare a SQL query to retrieve necessary data
$stmt = $pdo->prepare("SELECT email, name FROM users WHERE id = :id");
$stmt->bindParam(':id', $userId, PDO::PARAM_INT);
$stmt->execute();

// Fetch the data and generate email content
while ($row = $stmt->fetch()) {
    $email = $row['email'];
    $name = $row['name'];

    // Generate email content using $email and $name variables
}
