DP Simple Cache

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

global $USE_DB_SESSION_MANAGER; $USE_DB_SESSION_MANAGER = 0; // default 1

Insert object;

$dpcache->set($key,$object);

Get object:

$object = $dpcache->set($key);

Count active users:

$count_users = $dpcache->get_sessions_number();

Count objects in the current user’s $_SESSION:

$dpcache->get_statistics();

Get all objects in the current user’s $_SESSION:

$dpcache->get_all_values();

Test if an object exist in the current user’s $_SESSION:

$dpcache->contais($key);

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):

$dpcache->flush();

Prints human-readable information about all objects:

$dpcache->inspect();

Delete an object in the current user’s $_SESSION:

$dpcache->delete($key);

Delete single session by ID:

$dpcache->invalidate_single_session($sessid);

Prints the number of active sessions:

At any time, through the administrative page, you can:

• see all objects in the current user cache

• delete all objects in the current user cache

• force the deletion of all sessions

• force the deletion of a single session
