<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>
