What steps should be taken to troubleshoot and debug PHP scripts that utilize PHPMailer for sending emails?

To troubleshoot and debug PHP scripts that utilize PHPMailer for sending emails, you can start by checking the SMTP settings, ensuring that the email addresses are correctly formatted, and verifying that the PHPMailer library is properly included and initialized in your script. 

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

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

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

// Set SMTP settings
$mail->isSMTP();
$mail->Host = 'smtp.example.com';
$mail->SMTPAuth = true;
$mail->Username = 'your_username';
$mail->Password = 'your_password';
$mail->SMTPSecure = 'tls';
$mail->Port = 587;

// Set email content and recipients
$mail->setFrom('from@example.com', 'Your Name');
$mail->addAddress('recipient@example.com', 'Recipient Name');
$mail->Subject = 'Subject';
$mail->Body = 'Email content';

// Send email
if ($mail->send()) {
    echo 'Email sent successfully';
} else {
    echo 'Email sending failed: ' . $mail->ErrorInfo;
}
