How can the order of posts in the forum be changed from ascending to descending?

To change the order of posts in the forum from ascending to descending, you can modify the SQL query used to retrieve the posts by adding an "ORDER BY" clause with the desired sorting order (e.g., "ORDER BY post_date DESC"). This will ensure that the posts are displayed in descending order based on the post date.

// Original SQL query to retrieve posts in ascending order
$sql = "SELECT * FROM posts ORDER BY post_date ASC";

// Modified SQL query to retrieve posts in descending order
$sql = "SELECT * FROM posts ORDER BY post_date DESC";
