Are there best practices for optimizing MySQL queries in PHP to avoid nested loops?

Avoiding nested loops in MySQL queries in PHP can be achieved by using JOINs to retrieve data from multiple tables in a single query. This can reduce the number of queries executed and improve performance by fetching the necessary data in a more efficient manner. 

// Example of using JOIN to avoid nested loops in MySQL query
$query = "SELECT users.id, users.name, orders.order_id, orders.total_amount 
          FROM users 
          JOIN orders ON users.id = orders.user_id";

$result = mysqli_query($connection, $query);

if(mysqli_num_rows($result) > 0) {
    while($row = mysqli_fetch_assoc($result)) {
        // Process data here
    }
}
