Quick Zend Cache Setup

Here’s a quick solution to get a cache running on your Zend Framework install. It’s very simple and should provide a good solution for most small-scale sites.

You can put this code inside of your bootstrap file. I like to use the method style for invoking the bootstrapper.

// Disable auto buffer and instead leave it to the cache

Zend_Controller_Front::getInstance()->setParam('disableOutputBuffering', true);
$frontendOptionsCore = array(
    'automatic_serialization' => true,
    'lifetime' => 600
);

$frontendOptionsPage = array(
    'automatic_serialization' => true,
    'lifetime' => 600,
    'default_options' => array(
        'cache_with_get_variables' => true,
        'cache_with_session_variables' => true,
        'cache_with_cookie_variables' => true,
        'make_id_with_get_variables' => true,
        'make_id_with_session_variables' => true,
        'make_id_with_cookie_variables' => false
        )
    );

$backendOptions  = array('cache_dir' => APPLICATION_PATH . '/data/cache');
$coreCache = Zend_Cache::factory('Core', 'File', $frontendOptionsCore, $backendOptions);
$pageCache = Zend_Cache::factory('Page', 'File', $frontendOptionsPage, $backendOptions);

// Start running the page cache immediately
$pageCache->start();

// Set global cache objects
Zend_Registry::set('coreCache', $coreCache);
Zend_Registry::set('pageCache', $pageCache);

// Start running the DB/Core cache
Zend_Db_Table_Abstract::setDefaultMetadataCache(Zend_Registry::get('coreCache'));

// Disable auto buffer and instead leave it to the cache

Zend_Controller_Front::getInstance()->setParam('disableOutputBuffering', true);

$frontendOptionsCore = array(

'automatic_serialization' => true,

'lifetime' => 600

);

$frontendOptionsPage = array(

'automatic_serialization' => true,

'lifetime' => 600,

'default_options' => array(

'cache_with_get_variables' => true,

'cache_with_session_variables' => true,

'cache_with_cookie_variables' => true,

'make_id_with_get_variables' => true,

'make_id_with_session_variables' => true,

'make_id_with_cookie_variables' => false

)

);

$backendOptions = array('cache_dir' => APPLICATION_PATH . '/data/cache');

$coreCache = Zend_Cache::factory('Core', 'File', $frontendOptionsCore, $backendOptions);

$pageCache = Zend_Cache::factory('Page', 'File', $frontendOptionsPage, $backendOptions);

// Start running the page cache immediately

$pageCache->start();

// Set global cache objects

Zend_Registry::set('coreCache', $coreCache);

Zend_Registry::set('pageCache', $pageCache);

// Start running the DB/Core cache

Zend_Db_Table_Abstract::setDefaultMetadataCache(Zend_Registry::get('coreCache'));

What this snippet does is initialise two related caches – a core cache, and a page cache. The core cache (in this instance) is attached to our database table abstract class, which allows results to be stored as serialized strings. The page cache is invoked whenever template output is due to occur, and saves pre-rendered HTML for immediate output.

You can find all the documentation for tweaking your cache settings in the Zend_Cache documention.
