What are the best practices for passing the ID of a guestbook entry to a separate page for editing in PHP?

When passing the ID of a guestbook entry to a separate page for editing in PHP, it is best practice to use GET parameters in the URL to send the ID to the editing page. This allows for easy retrieval of the ID on the editing page using $_GET and ensures that the ID is securely passed without altering the database. 

// Guestbook entry page with edit link passing the ID
echo '<a href="edit_entry.php?id=' . $entry_id . '">Edit Entry</a>';

// edit_entry.php to retrieve the ID and perform editing
if(isset($_GET['id'])){
    $entry_id = $_GET['id'];
    
    // Use $entry_id for editing the specific guestbook entry
}
