Introduction to the usage of "global/php/Framework"

for example:
<?
$global=new framework("global","global");
$global->title="[title]";
$global->sql=new mysql("[ip]","[username]","[passwd]","[dbname]","utf8");
$global->sql=new mysql("localhost","root","868686","test","utf8");
$global->mongo=new Mongo("localhost:27017");
$global->mongodb=$global->mongo->selectDB("db");
$global->main();
?>


then, ModelMongoStore will assume that the framework has an attribute: mongodb. MongoStore will use this to finish all kinds of functions specifically designed for MongoStore.
