D(ifferent)P(lace) Simple Cache is a WordPress plugin to implement a simple cache of objects at session level.
dpwpsimplecache provides a global variable $dpcache, which is an instantiation of the class DP_Cache already set up to talk to the $_SESSION. Always use the global $dpcache variable (Remember to globalize $dpcache before using it in any custom functions).
If you don’t want to track sessions into db set the $USE_DB_SESSION_MANAGER global variable to 0
<pre><code> global $USE_DB_SESSION_MANAGER;
 $USE_DB_SESSION_MANAGER = 0; // default 1
</code></pre>
Insert object;
<pre><code> $dpcache->set($key,$object);
</code></pre>
Get object:
<pre><code> $object = $dpcache->set($key);
</code></pre>
Count active users:
<pre><code> $count_users = $dpcache->get_sessions_number();
</code></pre>
Count objects in the current user’s $_SESSION:
<pre><code> $dpcache->get_statistics();
</code></pre>
Get all objects in the current user’s $_SESSION:
<pre><code> $dpcache->get_all_values();
</code></pre>
Test if an object exist in the current user’s $_SESSION:
<pre><code> $dpcache->contais($key);
</code></pre>
Delete all objects. If the $all parameter is set to false the method delete only the current user’s $_SESSION, if true truncate the entire table (default false):
<pre><code> $dpcache->flush();
</code></pre>
Prints human-readable information about all objects:
<pre><code> $dpcache->inspect();
</code></pre>
Delete an object in the current user’s $_SESSION:
<pre><code> $dpcache->delete($key);
</code></pre>
Delete single session by ID:
<pre><code> $dpcache->invalidate_single_session($sessid);
</code></pre>
Prints the number of active sessions:
<pre><code> <?php echo dpscache_active_users(); ?>
</code></pre>
At any time, through the administrative page, you can:
<ul>
<li>see all objects in the current user cache</li>
<li>delete all objects in the current user cache</li>
<li>force the deletion of all sessions</li>
<li>force the deletion of a single session</li>
</ul>
