How can the code provided be improved for better readability and efficiency in PHP?

The code can be improved for better readability and efficiency by using more descriptive variable names, breaking down complex logic into smaller functions, and removing unnecessary repetition. 

// Improved code with better variable names and logic separation

function calculateTotalPrice($items) {
    $totalPrice = 0;

    foreach ($items as $item) {
        $price = $item['price'];
        $quantity = $item['quantity'];
        
        $totalPrice += $price * $quantity;
    }

    return $totalPrice;
}

$items = [
    ['name' => 'Item 1', 'price' => 10, 'quantity' => 2],
    ['name' => 'Item 2', 'price' => 20, 'quantity' => 1]
];

$totalPrice = calculateTotalPrice($items);
echo "Total Price: $totalPrice";
