What are some recommended PHP libraries for handling email functionality alongside database tasks?

When working with email functionality alongside database tasks in PHP, it is recommended to use libraries that simplify the process of sending emails and interacting with databases. Some popular libraries that can help with this are PHPMailer for sending emails and PDO (PHP Data Objects) for interacting with databases.

// Example code using PHPMailer and PDO

// Include PHPMailer library
require 'path/to/PHPMailer/PHPMailerAutoload.php';

// Create a new PHPMailer instance
$mail = new PHPMailer;

// Set up the email details
$mail->isSMTP();
$mail->Host = 'smtp.example.com';
$mail->SMTPAuth = true;
$mail->Username = 'your@example.com';
$mail->Password = 'yourpassword';
$mail->SMTPSecure = 'ssl';
$mail->Port = 465;
$mail->setFrom('from@example.com', 'Your Name');
$mail->addAddress('recipient@example.com', 'Recipient Name');
$mail->Subject = 'Subject of the email';
$mail->Body = 'Body of the email';

// Send the email
if(!$mail->send()) {
    echo 'Message could not be sent.';
    echo 'Mailer Error: ' . $mail->ErrorInfo;
} else {
    echo 'Message has been sent';
}

// Connect to the database using PDO
$dsn = 'mysql:host=localhost;dbname=mydatabase';
$username = 'username';
$password = 'password';

try {
    $pdo = new PDO($dsn, $username, $password);
    $pdo->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
} catch (PDOException $e) {
    echo 'Connection failed: ' . $e->getMessage();
}
