In what ways can logging actions and results help troubleshoot issues with PHP contact forms, especially in relation to email delivery?

Logging actions and results in PHP contact forms can help troubleshoot email delivery issues by providing a detailed record of the steps taken and the outcomes. By logging key events such as form submissions, email sending attempts, and any errors encountered, developers can easily track the flow of data and identify potential bottlenecks or issues in the process. This can help pinpoint where the problem lies, whether it's with the form submission, email configuration, or the recipient's email server. 

// Log actions and results for troubleshooting email delivery issues
$log_file = 'email_log.txt';

// Log form submission
$log_message = date('Y-m-d H:i:s') . ' - Form submitted' . PHP_EOL;
file_put_contents($log_file, $log_message, FILE_APPEND);

// Send email
if (mail($to, $subject, $message, $headers)) {
    $log_message = date('Y-m-d H:i:s') . ' - Email sent successfully' . PHP_EOL;
} else {
    $log_message = date('Y-m-d H:i:s') . ' - Failed to send email' . PHP_EOL;
}
file_put_contents($log_file, $log_message, FILE_APPEND);
