How can implementing a prefix system or a checkbox for marking threads as solved improve the efficiency of resolving issues in a PHP forum?

Issue: Without a clear way to mark threads as solved in a PHP forum, users may have difficulty finding solutions to their problems. Implementing a prefix system or a checkbox for marking threads as solved can improve efficiency by allowing users to quickly identify resolved issues. PHP code snippet:

// Add a checkbox to mark a thread as solved
echo '<input type="checkbox" name="solved" value="1"> Mark as solved';

// Check if the thread has been marked as solved
if(isset($_POST['solved']) && $_POST['solved'] == 1){
    // Update the thread status in the database
    $thread_id = $_POST['thread_id'];
    $query = "UPDATE threads SET solved = 1 WHERE id = $thread_id";
    // Execute the query
}
