PhpClass 'composer client' NOTFound

PhpClass 'official client' NOTFound: install the latest php_mongodb.dll extension corresponding to the official version for php7.0.4 in windows. the extension version is 1.1.6 and supports the highest version of MongoDB3.2 and php7.0 ,; you can see the MongoDB extension in phpinfo,
However, when the namespace is not used, the following error occurs in new guest client ();
Fatal error: Uncaught Error: Class 'warning client' not found in E: \ ...... why ?? Excuse me

Version support, for example (pay attention to the line mongodb1.1)
1. extended support for MOngoDB


2. extended support for php

Reply to discussion (solution)

I have never used it.

But how do you know there must be a consumer client class?
You need at least
Print_r (get_extension_funcs ('mongodb '));
Let's take a look at the functions provided in the extension.
Print_r (get_declared_classes ());
Check whether the pre-defined class has the class name you need (or similar ).

The official php.net documentation is used in this way by the new protocol client ()
I am not sure whether this type is available, is it true that I have not installed the corresponding VC?
Why can't I find vc14 online?

@ Xuzuning

Didn't I ask you to take a look?
What's so hard at hand?

Only a few things related to MongoDB

The reason is found because the old version of php_mongo.dll uses the MongoClient class for connection. The new version of php_mongodb.dll is connected using MongoDB \ Driver \ Manager. Note that the namespace of this class cannot be omitted.
This is the old reference document http://php.net/manual/zh/book.mongo.php
This is the new reference document http://php.net/manual/zh/book.mongodb.php
The usage of the new version is as follows:

$con    = new MongoDB\Driver\Manager('mongodb://127.0.0.1:27017');$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 '
';}
