Next in database.php is a starter function called get_posts(), which you will finish. (It's called in / index.php.) It takes no parameters and returns nothing, but uses the global $pdo object to get all comments from the database and store them in a global array called $posts (declared in /index.php.) Comments should be fetched such that newest comments are at the top. Create a query to get all the contents of the comments table. To do this, youll need to use the SELECT and ORDER BY commands (as well as a few others.) The newest comments should be at the top, which means you should order by descending ID. Execute the query. (no need for prepared statements since were not accepting user input.) Use a loop and the fetch method to get each row. Store each row in the $posts global array. Can someone pls help me how to do this...?.
