$objectSet = new ObjectSet();
$objectSet->add($object1); $objectSet->add($object2); $objectSet->add($object3);
$filteredObjects = $objectSet->filter(function ($object) { return $object->isActive(); });
$sortedObjects = $objectSet->orderBy('created_at');
$count = $objectSet->count();In these examples, we can see that the PHP Object Set library provides a simple and convenient way to manage collections of objects. The functions and methods provided by the library are designed to be easy to use and integrate seamlessly with other PHP code. The library is likely to be part of a larger package or framework, such as Laravel or Symfony.
