//flush a single cache item $cache = Zend\Cache\StorageFactory::adapterFactory('filesystem'); $cache->removeItem('my_cache_key'); //flush all cache items $cache->flush();
//flush a single cache item apc_delete('my_cache_key'); //flush all cache items apc_clear_cache();
//flush a single cache item $cache = new Memcached(); $cache->delete('my_cache_key'); //flush all cache items $cache->flush();In these examples, we can see that different PHP cache libraries have different methods to flush the cache. The first example uses the Zend Cache Library, the second uses APC cache, and the third uses Memcached. Determining the package library will depend on the specific cache library used in the project. Developers can check the documentation and configuration files to identify the cache library used and its methods for flushing the cache.
