PHP Class ' mongoclient ' not Found

The latest Php_mongodb.dll extension for php7.0.4 is installed under Windows for the current official version, which is 1.1.6, supports the highest version MongoDB3.2, supports php7.0, and can see MongoDB extension in Phpinfo ，
However, if you do not use a namespace, new Mongoclient () has the following error
Fatal error:uncaught error:class ' mongoclient ' not found in e:\ .... Why is this?? Excuse me

Version support such as (note mongodb1.1 that line)
1. Extended Support for MongoDB version


2. Extended Support for PHP version

Reply to discussion (solution)

No, not really.

But how do you know there must be a mongoclient class?
You need at least
Print_r (Get_extension_funcs (' MongoDB '));
Take a look at the functions that are available in the extension
Print_r (Get_declared_classes ());
See if there is a class name that you need (or similar) in a predefined class

Php.net's official documents are so used. New Mongoclient ()
I also do not know whether there is this kind, is not I do not install the corresponding VC?
What is the download address of Vc14, how to find it on the Internet

@xuzuning

Didn't I ask you to see it?
Is it so hard at hand?

It's just a few of those related to MongoDB.

Find the reason, because the old version of the Php_mongo.dll is to use the Mongoclient class to achieve the connection, the new version of the Php_mongodb.dll is to use Mongodb\driver\manager to connect; Notice that the class namespace cannot be omitted.
This is an older version of the reference document http://php.net/manual/zh/book.mongo.php
This is the new version of the reference document http://php.net/manual/zh/book.mongodb.php
Here's how to use the new version:

$con    = new Mongodb\driver\manager (' mongodb://127.0.0.1:27017 '); $query  = new Mongodb\driver\query ([]); $ cursor = $con->executequery (' Databasename.collectionname ', $query); $it     = new Iteratoriterator ($cursor); $it- >rewind (); while ($doc = $it->current ()) {Print_r ($doc); $it->next (); Echo '
';}
