What steps can be taken to mark a PHP forum thread as resolved or closed?

To mark a PHP forum thread as resolved or closed, you can add a status field to your database table for forum threads. When a thread is resolved or closed, update the status field to reflect this change. You can then display a "Resolved" or "Closed" label next to the thread title on the forum page based on the status field value.

// Update the status of a forum thread to mark it as resolved or closed
// Assuming $threadId is the ID of the thread to be updated

$status = 'resolved'; // or 'closed'
$sql = "UPDATE forum_threads SET status = :status WHERE id = :threadId";
$stmt = $pdo->prepare($sql);
$stmt->bindParam(':status', $status);
$stmt->bindParam(':threadId', $threadId);
$stmt->execute();
