Refresh Invalidate cache via CRON job

Often, invalidate cache status is found in Magento, and in such scenario we need to keep on refreshing the cache status.

To do this we can set a cron job that will check if cache in Invalid type, then it will refresh the cache.

To do this we can follow bellow steps:

Step1: We need to create “refresh-flush-cache.php” on root directory ”
/var/www/html/ ”

Below is file content.

error_reporting(E_ALL ^ E_NOTICE);
set_time_limit(0);
ini_set(‘memory_limit’,’1024M’);
ini_set(‘display_errors’,’1′);

$rootDir = “/var/www/html/”;

require_once($rootDir.”app/Mage.php”);
Mage::app()->setCurrentStore(Mage_Core_Model_App::ADMIN_STORE_ID);
Mage::app(“default”);

$types = Mage::app()->getCacheInstance()->getInvalidatedTypes();

echo “Scripts Starts at=>”.date(“d/m/Y H:i:s”);

foreach($types as $type)
{
echo “\n Cache Type=>”.$type->getId();
Mage::app()->getCacheInstance()->cleanType($type->getId());
}

echo “\n Scripts Ends at=>”.date(“d/m/Y H:i:s”);
?>

Step2: Now we have to set a cron for this file which will execute in every 30 min.
