In what ways can PHP developers streamline the process of fetching and displaying dynamic data from multiple database tables to avoid repetition and improve code readability?

One way PHP developers can streamline the process of fetching and displaying dynamic data from multiple database tables is by using JOIN queries to retrieve all necessary data in a single query instead of making multiple queries. This helps avoid repetition and improves code readability by reducing the number of database calls needed to fetch the required data. 

// Example of using a JOIN query to fetch data from multiple tables

$query = "SELECT users.username, orders.order_id, orders.total_amount 
          FROM users 
          INNER JOIN orders ON users.user_id = orders.user_id";

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

if (mysqli_num_rows($result) > 0) {
    while ($row = mysqli_fetch_assoc($result)) {
        echo "Username: " . $row['username'] . " | Order ID: " . $row['order_id'] . " | Total Amount: " . $row['total_amount'] . "<br>";
    }
} else {
    echo "No results found";
}
