What are some best practices for structuring PHP code when fetching data from a database using JOIN statements?

When fetching data from a database using JOIN statements in PHP, it is important to properly structure your code to ensure readability and maintainability. One best practice is to separate your database logic from your presentation logic by using a separate function or class to handle the database queries. Additionally, consider using prepared statements to prevent SQL injection attacks and sanitize user input before executing the query. 

// Example of structuring PHP code when fetching data from a database using JOIN statements

// Function to fetch data from the database using JOIN statements
function fetchDataFromDatabase() {
    $pdo = new PDO('mysql:host=localhost;dbname=mydatabase', 'username', 'password');
    
    $query = "SELECT t1.column1, t2.column2 FROM table1 t1 JOIN table2 t2 ON t1.id = t2.table1_id";
    $statement = $pdo->prepare($query);
    $statement->execute();
    
    $result = $statement->fetchAll(PDO::FETCH_ASSOC);
    
    return $result;
}

// Example usage
$data = fetchDataFromDatabase();
foreach ($data as $row) {
    echo $row['column1'] . ' - ' . $row['column2'] . '<br>';
}
