# Zend_Cache_Backend_Memcached_Namespace

Extends `Zend_Cache_Backend_Memcached` to allow for clearing of specific variables based

on their specified "namespace".

    // Vanilla Memcached

    $plain = new Zend_Cache_Backend_Memcached();

    

    // Namespaced Memcached

    $posts = new Zend_Cache_Backend_Memcached_Namespace(array(

        'namespace' => 'posts'

    ));

    

    // COMMAND                                 Memcached Data

    //

    $plain->save('Bob', 'firstName');       // ['firstName']        => 'Bob'

    

    $posts->save('Eric', 'firstName');      // ['firstName']        => 'Bob'

                                            // ['posts::firstName'] => 'Eric'

                                            // ['posts::__keys']    => array('posts::firstName')

    

    $posts->save('Clemmons', 'lastName');   // ['firstName']        => 'Bob'

                                            // ['posts::firstName'] => 'Eric'

                                            // ['posts::lastName']  => 'Clemmons'

                                            // ['posts::__keys']    => array('posts::firstName', 'posts::lastName')

    

    $posts->clean();                        // ['firstName']        => 'Bob'

    $plain->clean();                        // (everything's gone!)

## Usage

This simply modifies the `clean` functionality in `Zend_Cache_Backend_Memcached`

to only clean the current namespace, unless you pass in `Zend_Cache::CLEANING_MODE_ALL`.

### application.ini:

    resources.cachemanager.posts.frontend.name = "Class"

    resources.cachemanager.posts.frontend.options.cached_entity = "Posts"

    

    ; Because of "sanitization" of backends, we have to use a custom one

    resources.cachemanager.posts.backend.customBackendNaming = true

    resources.cachemanager.posts.backend.name = "Zend_Cache_Backend_Memcached_Namespace"

    

    ; This backend will be stored with keys like: "posts::$KEY"

    resources.cachemanager.posts.backend.options.namespace = 'posts'

### index.php

Clone this repo into your `vendors` directory and add it to your include path:

    set_include_path(implode(PATH_SEPARATOR, array(

        ...

        realpath(APPLICATION_PATH . '/../vendors/zend-memcached-namespaced'),

        ...

    );

### Example

    class Zend_Controller_PostsController extends Zend_Controller_Action

    {

        ...

        

        public function addPost()

        {

            $post = new Post();

            ...

            Posts::add($post);

            

            // Clean the posts cache

            $this->cache->clean();

            

            // Clean all data

            $this->cache->clean(Zend_Cache::CLEANING_MODE_ALL);

        }

        

    }
