In the context of a chat program, what are the best practices for organizing and retrieving chat messages from a database using PHP?

When organizing and retrieving chat messages from a database using PHP, it is important to properly structure the database schema to store messages efficiently. Use a timestamp to order messages chronologically and consider implementing pagination to retrieve messages in batches for better performance. 

// Example code to retrieve chat messages from a database in PHP
// Assuming you have a database connection established

// Retrieve messages in batches using pagination
$limit = 10; // Number of messages per page
$page = isset($_GET['page']) ? $_GET['page'] : 1; // Current page
$offset = ($page - 1) * $limit; // Calculate offset

$query = "SELECT * FROM chat_messages ORDER BY timestamp DESC LIMIT $limit OFFSET $offset";
$result = mysqli_query($connection, $query);

// Loop through the results and display messages
while ($row = mysqli_fetch_assoc($result)) {
    echo $row['message'] . " - " . $row['timestamp'] . "<br>";
}
