In what ways can code documentation and commenting be improved to facilitate collaboration and understanding when modifying or adapting existing PHP scripts for specific needs?

When modifying or adapting existing PHP scripts for specific needs, code documentation and commenting can be improved by providing clear explanations of the purpose of each function, variable, and section of code. Additionally, adding inline comments to explain complex logic or assumptions can help collaborators understand the code more easily. 

/**
 * Function to calculate the total price of items in a shopping cart
 * 
 * @param array $cartItems An array of items in the shopping cart
 * @return float The total price of all items in the cart
 */
function calculateTotalPrice($cartItems) {
    $totalPrice = 0;
    
    // Loop through each item in the cart and sum up the prices
    foreach ($cartItems as $item) {
        $totalPrice += $item['price'];
    }
    
    return $totalPrice;
}
