In what ways can the PHP code be refactored to improve its overall efficiency and readability?

Issue: The PHP code can be refactored by breaking down complex functions into smaller, more manageable functions. This will improve the code's readability and maintainability. Additionally, using meaningful variable names and comments will make the code easier to understand for other developers. Refactored PHP code: 

// Original code
function calculateTotalPrice($items) {
    $total = 0;
    foreach ($items as $item) {
        $total += $item['price'] * $item['quantity'];
    }
    return $total;
}

// Refactored code
function calculateTotalPrice($items) {
    $total = 0;
    foreach ($items as $item) {
        $total += calculateItemPrice($item);
    }
    return $total;
}

function calculateItemPrice($item) {
    return $item['price'] * $item['quantity'];
}
