Are there any potential security risks associated with sending raw emails in PHP?

Sending raw emails in PHP can pose security risks as it leaves the email vulnerable to header injection attacks. To mitigate this risk, it is recommended to use a library like PHPMailer or Swift Mailer, which handle email headers securely and prevent injection attacks. 

// Example using PHPMailer library to send secure emails
use PHPMailer\PHPMailer\PHPMailer;
use PHPMailer\PHPMailer\Exception;

require 'vendor/autoload.php';

$mail = new PHPMailer(true);

try {
    $mail->setFrom('from@example.com', 'Your Name');
    $mail->addAddress('recipient@example.com', 'Recipient Name');
    $mail->Subject = 'Subject Here';
    $mail->Body = 'Email body here';

    $mail->send();
    echo 'Email sent successfully';
} catch (Exception $e) {
    echo 'Message could not be sent. Mailer Error: ', $mail->ErrorInfo;
}
