How can the code be optimized to handle scenarios where multiple items from different providers are present in the shopping cart in PHP?

When dealing with multiple items from different providers in the shopping cart, it is important to optimize the code to handle these scenarios efficiently. One way to achieve this is by organizing the cart items based on their providers and processing them accordingly. This can be done by creating separate arrays or data structures for each provider's items and iterating through them to perform the necessary operations. 

// Sample code snippet to handle multiple items from different providers in the shopping cart

// Assuming $cartItems is an array of items with 'provider' key indicating the provider
$providerItems = [];

// Organize cart items based on their providers
foreach ($cartItems as $item) {
    $provider = $item['provider'];
    
    if (!isset($providerItems[$provider])) {
        $providerItems[$provider] = [];
    }
    
    $providerItems[$provider][] = $item;
}

// Process items for each provider
foreach ($providerItems as $provider => $items) {
    // Perform operations specific to each provider
    foreach ($items as $item) {
        // Process item
        // Example: calculate total price, apply discounts, etc.
    }
}
