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'));
