how to make variables in pre_controller hooks global to all controllers?

Question

in my pre_controller hook i have this code for doctrine:

$manager = Doctrine_Manager::getInstance(); $conn = Doctrine_Manager::connection($db[$active_group][‘dsn’]);

then in my controller i have this code to use doctrine connection i’ve created:

$conn->export->createTable(‘test’, array(‘name’ => array(‘type’ => ‘string’))); $conn->execute(‘INSERT INTO test (name) VALUES (?)’, array(‘jwage’));

but $conn is undefined so it wont work. if i put the code in the pre_controller hook it will work.

how can i make variables i declare in hooks available for all controllers so that i dont have to create a new connection all the time?
