<h3>Example usage:</h3>
<pre><code><?php if ( ! WP_Fragment_Cache::output( $wp_query_or_blockname, $duration ) ): ?>

  //content to be cached

  <?php WP_Fragment_Cache::store(); ?>
<?php endif; ?>
</code></pre>
<h4>Parameters:</h4>
<p><strong>$wp_query_or_blockname</strong><br />
(mixed/string) (optional) a WP_Query(WP_Comment_Query) result or a string.<br />
Default: the file and the line where the call was initiated(e.g. widgets/most-commented.php:18).</p>
<p><strong>$duration</strong><br />
(int/string) (optional) Defines how many seconds to keep the cache for. If you pass 0 the cache will not expire. If you pass  the string “only_today” the cache will expire at the end of the current day. You can use <a href="https://codex.wordpress.org/Transients_API#Using_Time_Constants" rel="nofollow ugc">WordPress Time Constants</a>.<br />

<p>Adds ability to globally cache certain segments of code.</p>
<p>WP Cache and some other caching plugins work amazingly well, however, their benefits are limited in sites with a large percentage of logged in users.  While working on these projects, we, Voce Connect, found the need for a better caching solution.  We needed to easily cache rendered portions of the theme that were the same for each user without caching other portions that may have user specific content.  The solution was to come up with a plugin that could be easily integrated into a theme to help cache these blocks of content.</p>
<p>Requirements:</p>
<ul>
<li>WordPress 2.8 or higher</li>
<li>“php5” – I’m a big proponent of dropping the php4 compatibility of WordPress due to the improved OO support.  Because of this, I prefer to write my plugins in php5 form in hopes to help push the community along.</li>
</ul>


WP Cache Block
