无法使用PHP在MongoDB上选择DB

已采纳

I'm asking this question because I couldn't find the answers.

I am using PHP 7.2 on XAMPP and 1.5.2 MongoDB Driver.

I created performanceWeb DB on my MongoDB server as you can see below:

Since I was getting an error while querying, I tried a simple code and it's not getting the DB (and therefore the collection):

$m = new MongoDB\Driver\Manager("mongodb://localhost:27017");     
    // select a collection

    if ($m == NULL){
        echo "m is NULL</br>";
    }

    if ($m->performanceWeb == NULL){
        echo "DB is NULL</br>";
    }

    if ($m->performanceWeb->usuarios == NULL){
        echo "collection NULL</br>";
    }

As you can see the result:

So, what am I doing wrong? Can you see the mistake?

Thank you very much.

    You have to connect to mongo as Client, You connecting as Manager.

    Please try following codes.

    $m = new MongoDB\Driver\Client("mongodb://localhost:27017");     
    // select a collection
    
    if ($m == NULL){
        echo "m is NULL</br>";
    }
    
    if ($m->performanceWeb == NULL){
        echo "DB is NULL</br>";
    }
    
    if ($m->performanceWeb->usuarios == NULL){
        echo "collection NULL</br>";
    }
