How can debugging techniques be used to troubleshoot issues with PHP scripts that involve sending emails?

To troubleshoot email sending issues in PHP scripts, you can use debugging techniques like checking for errors in the email configuration settings, ensuring the email function is properly called, and checking for any syntax errors in the email message. You can also use tools like error logs or try sending emails to a different email address to see if the issue is specific to a particular recipient. 

// Example PHP code snippet to troubleshoot email sending issues
// Check if the email function is properly called
if (mail($to, $subject, $message)) {
    echo 'Email sent successfully!';
} else {
    echo 'Failed to send email. Check your email configuration settings.';
}
