- * PDO Cache Handler
- * Allows you to store Smarty Cache files into your db.
- * Example table :
- * CREATE TABLE `smarty_cache` (
- * `id` char(40) NOT NULL COMMENT 'sha1 hash',
- * `name` varchar(250) NOT NULL,
- * `cache_id` varchar(250) DEFAULT NULL,
- * `compile_id` varchar(250) DEFAULT NULL,
- * `modified` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP,
- * `expire` timestamp NOT NULL DEFAULT '0000-00-00 00:00:00',
- * `content` mediumblob NOT NULL,
- * PRIMARY KEY (`id`),
- * KEY `name` (`name`),
- * KEY `cache_id` (`cache_id`),
- * KEY `compile_id` (`compile_id`),
- * KEY `modified` (`modified`),
- * KEY `expire` (`expire`)
- * ) ENGINE=InnoDB
- * Example usage :
- * $cnx = new PDO("mysql:host=localhost;dbname=mydb", "username", "password");
- * $smarty->setCachingType('pdo');
- * $smarty->loadPlugin('Smarty_CacheResource_Pdo');
- * $smarty->registerCacheResource('pdo', new Smarty_CacheResource_Pdo($cnx, 'smarty_cache'));
