/**
* MySQL Resource
* Resource Implementation based on the Custom API to use
* MySQL as the storage resource for Smarty's templates and configs.
* Note that this MySQL implementation fetches the source and timestamps in
* a single database query, instead of two separate like resource.mysql.php does.
* Table definition:
* <pre>CREATE TABLE IF NOT EXISTS `templates` (
* `name` varchar(100) NOT NULL,
* `modified` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP,
* `source` text,
* PRIMARY KEY (`name`)
* ) ENGINE=InnoDB DEFAULT CHARSET=utf8;</pre>
* Demo data:
* <pre>INSERT INTO `templates` (`name`, `modified`, `source`) VALUES ('test.tpl', "2010-12-25 22:00:00", '{$x="hello
* world"}{$x}');</pre>
*
