Cache

There are two caching mechanisms in RedBeanPHP, the Query Cache and the Bean Cache. I recommend to use the Query Cache, the Bean Cache is a plugin and it makes RedBeanPHP somewhat more complex to use.

Query Cache

In RedBeanPHP 3.4 you can use a very easy-to-use caching system: the Query Writer Cache. This caching mechanism will return the same result set for identical query-value pairs. The cache gets automatically flushed everytime something other than a select query is fired (i.e. an INSERT or DELETE). This means that this is a relatively safe cache to use. Issue the following statement to activate the Query Writer Cache:

    R::useWriterCache(true); (3.5.1+)
    
    //or...

    R::$writer->setUseCache(true);

Bean Cache

RedBeanPHP offers a Bean Cache. The bean cache can be configured like this:



    $cachedOODB = new RedBean_Plugin_Cache($t->getWriter());

To allow the facade to use the cache (note that $t is a toolbox instance RedBean_ToolBox):

    $t = R::$toolbox; //obtain old toolbox
    R::configureFacadeWithToolbox(new RedBean_ToolBox(
    $cachedOODB,
    $t->getDatabaseAdapter(),
    $t->getWriter()));

To flush cache:



    $cache->flushAll();

You can also choose to flush cached beans of a given type:



    $cache->flush($type);
