在yii2中找不到MongoDB \ Driver \ Manager'

Question

I am using php7.1.5(latest) and add mongodb extension with the help of below link http://php.net/manual/en/mongodb.installation.windows.php. Using mongodb driver version as 1.2.9 add dll file in php/ext folder. I check phpinfo() mongodb extension is added. But when i access mongodb like below

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

It will throw error like MongoDB\Driver\Manager' not found.

I try to add mongodb extension in php.ini file like below formats, but it will not work

extension=php_mongodb.dll, extension=mongodb.dll

i am using apache version 2.4.25

Answer 1

Add a backslash in front, as the class is in the Global Namespace and not under yii

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