 * If a string key in the given items matches a string key in the original collection,
 * the given items's value will overwrite the value in the original collection:
 */
$collection = collect(['product_id' => 1, 'price' => 100]);
$merged = $collection->merge(['price' => 200, 'discount' => false]);
