How can one ensure the security of passing parameters in a link for data editing in PHP?

To ensure the security of passing parameters in a link for data editing in PHP, one should avoid passing sensitive data directly in the URL. Instead, use a unique identifier (e.g., a record ID) to retrieve the data securely from the server. Additionally, consider implementing server-side validation to check the user's permission before allowing any data editing. 

// Example of passing a record ID in a link for data editing
<a href="edit.php?id=<?php echo urlencode($record_id); ?>">Edit Record</a>

// In edit.php, retrieve the record ID securely
$record_id = isset($_GET['id']) ? $_GET['id'] : null;
// Perform server-side validation and permission checks before allowing data editing
