How can the PHP code be optimized for better readability and maintainability, based on the suggestions provided in the forum thread?

Issue: The PHP code can be optimized for better readability and maintainability by breaking it down into smaller, more manageable functions and using meaningful variable names. Solution: To improve the readability and maintainability of the PHP code, we can break down the logic into smaller functions and use descriptive variable names. This will make the code easier to understand and maintain in the future. 

function calculateTotalPrice($items) {
    $totalPrice = 0;
    
    foreach ($items as $item) {
        $totalPrice += $item['price'];
    }
    
    return $totalPrice;
}

function displayTotalPrice($totalPrice) {
    echo "Total price: $" . $totalPrice;
}

$items = [
    ['name' => 'Item 1', 'price' => 10],
    ['name' => 'Item 2', 'price' => 20],
    ['name' => 'Item 3', 'price' => 30]
];

$totalPrice = calculateTotalPrice($items);
displayTotalPrice($totalPrice);
