What are the best practices for limiting and ordering data in PHP queries to achieve desired results?

When working with SQL queries in PHP, it is important to use the LIMIT clause to restrict the number of rows returned and the ORDER BY clause to specify the order in which the results should be displayed. By combining these clauses effectively, you can achieve the desired results in your queries. 

// Example query to limit and order data in PHP
$query = "SELECT * FROM users ORDER BY created_at DESC LIMIT 10";
$result = mysqli_query($connection, $query);

if(mysqli_num_rows($result) > 0) {
    while($row = mysqli_fetch_assoc($result)) {
        // Process each row of data
    }
} else {
    echo "No results found.";
}
