Are there any specific PHP libraries or classes recommended for simplifying email sending processes and handling special characters?

When sending emails with PHP, it is important to properly handle special characters to ensure that the email content is displayed correctly. To simplify the email sending process and handle special characters, it is recommended to use the PHPMailer library. PHPMailer provides a secure and easy way to send emails with support for special characters and various email protocols.

// Include the PHPMailer library
use PHPMailer\PHPMailer\PHPMailer;
use PHPMailer\PHPMailer\Exception;

require 'vendor/autoload.php';

// Create a new PHPMailer instance
$mail = new PHPMailer(true);

// Set up the email parameters
$mail->isSMTP();
$mail->Host = 'smtp.example.com';
$mail->SMTPAuth = true;
$mail->Username = 'your@example.com';
$mail->Password = 'your_password';
$mail->SMTPSecure = 'tls';
$mail->Port = 587;

$mail->setFrom('from@example.com', 'Your Name');
$mail->addAddress('recipient@example.com', 'Recipient Name');
$mail->Subject = 'Subject with special characters é';
$mail->Body = 'Email content with special characters é';

// Send the email
if($mail->send()) {
    echo 'Email sent successfully';
} else {
    echo 'Email could not be sent';
}
