How can the inability to view the email source code affect troubleshooting and debugging PHP email sending issues?

When troubleshooting PHP email sending issues, not being able to view the email source code can make it difficult to identify errors in the email headers, content, or attachments. To solve this issue, you can use the "error_log" function in PHP to log the email content to a file for review. 

// Send email
if (mail($to, $subject, $message, $headers)) {
    // Log email content to a file for debugging
    error_log("To: $to\nSubject: $subject\nMessage: $message\nHeaders: $headers", 3, "email_log.txt");
    echo "Email sent successfully!";
} else {
    echo "Failed to send email. Please check your email settings.";
}
