<p>Flush Opcache with Varnish automatically flushes the PHP Opcache when one of the “Empty Cache” buttons that Mika Epstein’s excellent <a href="https://wordpress.org/plugins/varnish-http-purge/" rel="ugc">Varnish HTTP Cache</a> creates are clicked.</p>
<p>If the <a href="https://wordpress.org/plugins/flush-opcache/" rel="ugc">WP Opcache</a> plugin is installed it is used to flush the opcache to let the opcache be re-warmed according to your WP Opcache settings, (and you can turn off WP Opcache’s “Flush PHP Opcache” button from the Admin toolbar).</p>
<p>If <a href="https://wordpress.org/plugins/wp-super-cache/" rel="ugc">WP Super Cache</a> is installed then the WP Super Cache cache will be cleared as well.</p>

<p>Docket Cache is a persistent WordPress Object Cache that stores cached data as plain PHP code. It is designed as an alternative for sites that do not have access to Redis or Memcached.</p>
<p>Most file-based caching plugins use <a href="https://www.php.net/manual/en/function.serialize.php" rel="nofollow ugc">serializing</a> and <a href="https://www.php.net/manual/en/function.unserialize.php" rel="nofollow ugc">unserializing</a> to save PHP objects to flat files. Docket Cache takes a different approach by converting objects into plain PHP code. This makes data retrieval faster and improves overall performance, especially when Zend OPcache is enabled.</p>
<p>For more information, please refer to the documentation on <a href="https://docs.docketcache.com/resources/caching-in-wordpress" rel="nofollow ugc">Caching In WordPress</a>.</p>
<h3>Why use this plugin?</h3>
<p>For reliable persistent Object Cache in WordPress, <a href="https://redis.io/" rel="nofollow ugc">Redis</a> or <a href="https://memcached.org/" rel="nofollow ugc">Memcached</a> are the top choices. However, they require server knowledge and are rarely available on low-cost or shared hosting plans.</p>
<p>The alternative is to store object caches in files. In WordPress, exporting PHP objects is not straightforward. Most file-based caching plugins rely on serialising and unserialising objects to store and retrieve data.</p>
<p>Docket Cache takes a better approach by turning the object cache into plain PHP code. This is faster because WordPress can use the cache directly without additional processing.</p>
