use Zend\Cache\StorageFactory; $cache = StorageFactory::adapterFactory('apc'); $instance = $cache::getInstance();
use Symfony\Component\Cache\Adapter\ApcuAdapter; $cache = new ApcuAdapter(); $instance = $cache->getInstance();
use Illuminate\Support\Facades\Cache; $cache = Cache::store('apc'); $instance = $cache->getInstance();In these examples, we can see that `getInstance()` is used on different caching classes or adapters from different libraries, including Zend Cache, Symfony Cache Component, and Laravel Cache. Overall, `getInstance()` is a useful method to retrieve an instance of a caching class and can be used with various caching libraries in PHP.
