What best practices should be followed when handling email functionality in PHP scripts to ensure reliable delivery and avoid common errors like the one mentioned in the forum thread?

The common error mentioned in the forum thread is related to email delivery issues in PHP scripts. To ensure reliable delivery and avoid such errors, it is recommended to use a reliable SMTP server for sending emails, properly set up SPF and DKIM records for email authentication, handle errors and exceptions in the email sending process, and sanitize user input to prevent injection attacks. 

// Example PHP code snippet for sending emails using PHPMailer with SMTP server configuration

use PHPMailer\PHPMailer\PHPMailer;
use PHPMailer\PHPMailer\Exception;

require 'vendor/autoload.php'; // Include PHPMailer library

// Instantiate PHPMailer
$mail = new PHPMailer(true);

try {
    // Server settings
    $mail->isSMTP();
    $mail->Host = 'smtp.example.com';
    $mail->SMTPAuth = true;
    $mail->Username = 'your_smtp_username';
    $mail->Password = 'your_smtp_password';
    $mail->SMTPSecure = PHPMailer::ENCRYPTION_STARTTLS;
    $mail->Port = 587;

    // Recipient
    $mail->setFrom('from@example.com', 'Your Name');
    $mail->addAddress('recipient@example.com', 'Recipient Name');

    // Content
    $mail->isHTML(true);
    $mail->Subject = 'Subject';
    $mail->Body = 'Email body';

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