How can one troubleshoot issues with data not being displayed correctly in PHP form fields?

Issue: If data is not being displayed correctly in PHP form fields, it could be due to incorrect handling of the data retrieval or display process. To troubleshoot this issue, ensure that the data is properly fetched from the database or source, sanitized if necessary, and then displayed in the form fields using the correct PHP syntax. PHP Code Snippet: 

<?php
// Assuming $data contains the retrieved data
$data = "example data";

// Sanitize the data if necessary
$sanitized_data = htmlspecialchars($data);

// Display the data in a form field
echo "<input type='text' name='field_name' value='$sanitized_data'>";
?>
