How can debugging techniques be effectively utilized to identify and resolve issues in PHP email sending scripts?

Issue: One common issue with PHP email sending scripts is incorrect configuration settings, such as SMTP server details or sender email address. To solve this issue, ensure that the SMTP server details are correctly configured in the PHP script and that the sender email address is valid. 

// Set the SMTP server details
$smtp_host = 'smtp.example.com';
$smtp_port = 587;
$smtp_username = 'username@example.com';
$smtp_password = 'password';

// Set the sender email address
$from_email = 'sender@example.com';
$from_name = 'Sender Name';

// Send email using PHPMailer
$mail = new PHPMailer;
$mail->isSMTP();
$mail->Host = $smtp_host;
$mail->Port = $smtp_port;
$mail->SMTPAuth = true;
$mail->Username = $smtp_username;
$mail->Password = $smtp_password;
$mail->setFrom($from_email, $from_name);
// Add recipient, subject, body, etc.
$mail->send();
