Using Magento cache to save custom key value data

Using Magento cache to save custom key value data

• You can connect your cache items to the default cache tags of magento for example BLOCK_HTML. This will ensure that your items will be removed, when magento removes block_html cache.

//Initiate Cache class
$cache = Mage::app()->getCache();

//Get Item
$cachedItem = $cache->load($key);

//Save Item
$cache->save($value, $key, $tags = array(), $lifeTime=null);

//Remove Item
$cache->remove($key);

//Remove all items with the given tags
$cache->clean($tags = array();
