What are some best practices for handling email sending in PHP to avoid potential errors or complications?

When sending emails in PHP, it is important to handle potential errors and complications to ensure successful delivery. One common best practice is to use a reliable email library like PHPMailer, which provides robust features for sending emails securely and efficiently. Additionally, always sanitize user input to prevent injection attacks and validate email addresses before sending. Lastly, consider implementing error handling mechanisms to catch and log any issues that may arise during the email sending process. 

// Example using PHPMailer library for sending emails
use PHPMailer\PHPMailer\PHPMailer;
use PHPMailer\PHPMailer\Exception;

require 'vendor/autoload.php';

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

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

// Set the sender and recipient
$mail->setFrom('your@example.com', 'Your Name');
$mail->addAddress('recipient@example.com', 'Recipient Name');

// Set the email subject and body
$mail->Subject = 'Test Email';
$mail->Body = 'This is a test email';

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