Notes on using HashTable inside a horde app - Examples as typed in the horde php console

You need to configure a hash table first - there is a `HashTable`_ tab in the Horde config.
If you use Redis, you need the nrk channel Predis package first.

----------------------------------
 Retrieving a HashTable Instance
----------------------------------

::

 $hashtable = $GLOBALS['injector']->getInstance('Horde_HashTable');

----------------------------------
 Setting a key and a scalar value
----------------------------------

::

 $hashtable->set('key1', 'value1');

-----------------------------------------------------
 Setting a key and a structured value by serializing
-----------------------------------------------------

::

 // Mind using Horde_Pack instead
 $hashtable = $injector->getInstance('Horde_HashTable');
 
 $data = array('foo', 'bar');
 $packed = serialize($data);
 
 $hashtable->set('packed', $packed);
 $retrieved = $hashtable->get('packed');
 print $retrieved;
 print_r(unserialize($retrieved));

--------------------------------------
 Checking if a key exists, retrieving
--------------------------------------

::

 if ($hashtable->exists('key1')) {
     $result = $hashtable->get('key1');
 }
