            $sql = "SELECT user, comment, date FROM comments ORDER BY date DESC";

            $query = mysqli_query($conn, $sql);

Implementing a reply functionality to comments requires a bit of restructuring of your database and code to support comment threading. Here’s a general guide on how you could achieve this:

Step 1: Modify Database Structure

First, you need to modify the comments table to allow replies. A simple way to do this is by adding a parent comment ID to each comment using sql.

ALTER TABLE comments ADD parent_id INT DEFAULT 0;

Here, parent_id will be 0 for top-level comments and the comment ID of the parent comment for replies.

Step 2: Add Reply Form

You can add a reply form beneath each comment. In your PHP code where you are looping through comments, add a form like this:

echo    "<section>
            <form action='' method='post'>
                <input type='hidden' name='parent_id' value='$id'>
                <textarea name='reply_comment' required></textarea>
                <button type='submit' name='reply_submit'>Reply</button>

Make sure you have the comment ID available as $id in this loop.

Step 3: Handle Reply Submission

In your PHP code where you handle form submissions, add logic to handle replies:

if(isset($_POST['reply_submit'])) {
    $parent_id = $_POST['parent_id'];
    $reply_comment = $_POST['reply_comment'];

    $sql = "INSERT INTO comments (comment, user, date, parent_id) VALUES ('$reply_comment', '$username', NOW(), '$parent_id')";
    $query = mysqli_query($conn, $sql) or die('Could not connect to the database');

Step 4: Display Replies

You’ll need to update the way you fetch and display comments to handle threading. This can be a bit more complex, depending on how you want to structure replies. A simple way is to create a recursive function that fetches and displays all child comments for a given parent comment.

Good luck
