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

The code provided in the forum thread can be improved for better readability and efficiency by using more descriptive variable names, adding comments to explain the logic, and optimizing the loop structure. Additionally, using functions to encapsulate repetitive tasks can make the code more modular and easier to maintain. 

// Improved code with better variable names and comments

function calculate_total($items) {
    $total = 0;
    
    foreach ($items as $item) {
        $price = $item['price'];
        $quantity = $item['quantity'];
        
        $subtotal = $price * $quantity;
        $total += $subtotal;
    }
    
    return $total;
}

// Example usage
$items = [
    ['price' => 10, 'quantity' => 2],
    ['price' => 5, 'quantity' => 3]
];

$total = calculate_total($items);
echo "Total: $total";
