The CakePHP framework has excellent support for caching and can be easily used with MemCachier as the provider. To setup CakePHP with MemCachier, you'll need to edit the file app/Config/bootstrap.php and add the following lines:

Cache::config('default', array(
    'engine' => 'Memcached',
    'prefix' => 'mc_',
    'duration' => '+7 days',
    'compress' => false,
    'persistent' => 'memcachier',
    'servers' => explode(',', getenv('MEMCACHIER_SERVERS')),
    'login' => getenv('MEMCACHIER_USERNAME'),
    'password' => getenv('MEMCACHIER_PASSWORD'),
    'serialize' => 'php'

The values for MEMCACHIER_SERVERS, MEMCACHIER_USERNAME, and MEMCACHIER_PASSWORD are listed on your cache overview page. Make sure to add them to your environment.

After that, you should be able to use caching throughout your application like so:

class Post extends AppModel {

    public function newest() {
        $model = $this;
        return Cache::remember('newest_posts', function() use ($model){
            return $model->find('all', array(
                'order' => 'Post.updated DESC',
                'limit' => 10
        }, 'longterm');

The above will fetch the value associated with the key newest_posts from the cache if it exists. Otherwise, it will execute the function and SQL query, storing the result in the cache using the newest_posts key.
