zend_db query on connect

I want the query 'SET NAMES utf8' to 开发者_开发知识库execute before any other queries.

But, if I execute it in the beginning of my app, it forces Zend_Db to connect to the Database, even if I'm not running any other queries. It isn't cool: My app processes lots of requests without any queries, only using cache.

How to ask Zend_Db to run 'SET NAMES utf8' right after connection?

Sure, simply pass the 'charset' option in with the adapter params. You can do this via Zend_Config or in code:

$params = array(
    'host'           => '127.0.0.1',
    'username'       => 'webuser',
    'password'       => 'xxxxxxxx',
    'dbname'         => 'test',
    'charset'        => 'utf8'
);

$db = Zend_Db::factory('Pdo_Mysql', $params);
