Symfony找不到mongodb驱动程序（DLL）

Question

I've installed the mongodb driver (php_mongodb.dll). The file is inside xampp\php\ext. I've used it before with simple connections and queries against my mongodb server and it works perfectly.

To make the connection with mongo I use this simple line:

$conn = new MongoDB\Driver\Manager("mongodb://localhost:27017");

However, when I try to use it in my symfony project, I get this error:

Attempted to load class "Manager" from namespace "AlimentosBundle\Controller\MongoDB\Driver". Did you forget a "use" statement for another namespace?

I'm very beginner using symfony. Should I import also the DLL inside the symfony project? If not, how could I force Symfony to find the DLL?

I know that doctrine/mongodb bundle actually exists, but I just wanted to try some simple connections, is possible to do it without that bundle?

You miss an initial slash. Try this:

$conn = new \MongoDB\Driver\Manager("mongodb://localhost:27017");

instead of:

$conn = new MongoDB\Driver\Manager("mongodb://localhost:27017");

Obviously, as suggested, you can import the class and use without the namespace, as example:

use  MongoDB\Driver\Manager;

...

$conn = Manager("mongodb://localhost:27017");

Hope this help
