How can debugging techniques be effectively used to troubleshoot PHP email sending issues?

To troubleshoot PHP email sending issues, you can use debugging techniques such as checking error logs, verifying SMTP settings, and testing the email sending functionality with different email addresses. Additionally, you can use PHP's built-in functions like error_reporting() and var_dump() to identify any potential issues in your code. 

// Example code snippet to troubleshoot PHP email sending issues

error_reporting(E_ALL); // Enable error reporting to catch any errors

// Your email sending code here
$to = "recipient@example.com";
$subject = "Test Email";
$message = "This is a test email.";
$headers = "From: sender@example.com";

if (mail($to, $subject, $message, $headers)) {
    echo "Email sent successfully";
} else {
    echo "Email sending failed";
}
