How can I programmatically flush Magento’s Cache?

by

The question:

I’m automating release configurations by bootstrapping Mage in several release scripts. At the end of the scripts, I need to flush Magento’s cache.

Is there a way to flush the cache using one of the Mage classes or methods?

The Solutions:

Below are the methods you can try. The first solution is probably the best. Try others if the first one doesn’t work. Senior developers aren’t just copying/pasting – they read the methods carefully & apply them wisely to each case.

Method 1

Please try the following code to flush the cache programatically

Mage::app()->cleanCache()

or

Mage::app()->getCacheInstance()->flush();

Method 2

If you really wanted to you could also clean just one or more cache types. This is actually how the admin section does it. Under Mage_Adminhtml_CacheController::massRefreshAction

You can see that it loops through all the parameters types and calls the following

$tags = Mage::app()->getCacheInstance()->cleanType($type);
Mage::dispatchEvent('adminhtml_cache_refresh_type', array('type' => $type));
$updatedTypes++;

Possible types are as follows:

  1. config
  2. layout
  3. block_html
  4. translate
  5. collections
  6. eav
  7. config_api
  8. config_api2
  9. full_page

And these can be returned by calling Mage::app()->getCacheInstance()->getTypes()

Method 3

A quick external script to clear all cache:

<?php

require_once './app/Mage.php';
umask(0);
Mage::app('default');
Mage::app()->setCurrentStore(Mage_Core_Model_App::ADMIN_STORE_ID);

try {
    $allTypes = Mage::app()->useCache();
    foreach($allTypes as $type => $value) {
        Mage::app()->getCacheInstance()->cleanType($type);
        Mage::dispatchEvent('adminhtml_cache_refresh_type', array('type' => $type));
        echo "{$type} </br>";
    }
    echo 'done';
} catch (Exception $e) {
    echo $e->getMessage();
}

Method 4

Our we could use n98-magerun. Especially since you should never flush the cache during execution of deployment scripts. Also look at the sys:setup:incremental subcommand for more controlled execution of the Magento setup scripts.

Method 5

If you Really need to clear all cache storages means use the following code,

Mage::app()->getCacheInstance()->flush();

Here Flush function calls the default magento cache functionality, If you need more clarifications means refer the following url.
