What are the potential challenges of using client-side JavaScript to delete content from a DIV element in a PHP chat application?

One potential challenge of using client-side JavaScript to delete content from a DIV element in a PHP chat application is ensuring that the deletion is reflected in the server-side data. To address this, you can send an AJAX request to the server to update the chat data after the deletion is done on the client-side.

// PHP code to handle deletion of content from a DIV element in a chat application
if(isset($_POST['delete_message_id'])) {
    $message_id = $_POST['delete_message_id'];
    
    // Code to delete the message from the database here
    
    // Return a success message to the client-side
    echo json_encode(array('success' => true));
}
