What are some best practices for efficiently storing and organizing data from multiple tables in PHP?

When storing and organizing data from multiple tables in PHP, it is best practice to use SQL JOIN queries to retrieve data from multiple tables in a single query. This helps reduce the number of queries executed and improves performance. Additionally, using proper indexing on the database tables can also help improve query performance. 

// Example of using SQL JOIN to retrieve data from multiple tables
$query = "SELECT users.username, orders.order_id, orders.total_amount 
          FROM users
          JOIN orders ON users.user_id = orders.user_id";
$result = mysqli_query($connection, $query);

// Loop through the results
while($row = mysqli_fetch_assoc($result)) {
    // Process the data as needed
    echo $row['username'] . " made an order with ID " . $row['order_id'] . " totaling " . $row['total_amount'] . "<br>";
}
