Are there any specific PHP functions or methods that can help with organizing and displaying data from multiple database tables?

When dealing with data from multiple database tables, one common approach is to use SQL JOIN queries to combine related data into a single result set. PHP provides functions like mysqli_query() or PDO::query() to execute SQL queries and fetch data from multiple tables. Additionally, you can use functions like mysqli_fetch_assoc() or PDOStatement::fetch() to retrieve and organize the data in a structured format before displaying it on the webpage. 

// Example code snippet using PDO to fetch and display data from multiple tables

// Connect to the database
$pdo = new PDO("mysql:host=localhost;dbname=mydatabase", "username", "password");

// Prepare SQL query with JOIN to fetch 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";

// Execute the query
$stmt = $pdo->query($query);

// Fetch and display the data
while ($row = $stmt->fetch(PDO::FETCH_ASSOC)) {
    echo "Username: " . $row['username'] . "<br>";
    echo "Order ID: " . $row['order_id'] . "<br>";
    echo "Total Amount: $" . $row['total_amount'] . "<br><br>";
}
