What are some best practices for organizing PHP code to make it easier to understand and maintain?

To make PHP code easier to understand and maintain, it is important to follow best practices such as using proper naming conventions, organizing code into logical sections, avoiding duplication, and commenting code effectively. 

// Example of organizing PHP code into logical sections with comments

// Define functions
function calculateTotal($price, $quantity) {
    return $price * $quantity;
}

function displayTotal($total) {
    echo "Total: $" . $total;
}

// Main code
$price = 10;
$quantity = 5;

$total = calculateTotal($price, $quantity);

displayTotal($total);
