MongoClient Class vs. MongoDB\Driver\Manager Class

Question

I want to get your recommend about my web project. I use PHP and MongoDB but I was confused when I read this sentence from php documentation.

This extension that defines this class is deprecated. Instead, the MongoDB extension should be used. Alternatives to this class include: MongoDB\Driver\Manager

I already used MongoClient Class for CRUD but after reading that sentence, I tried to migrate MongoClient to MongoDB\Driver\Manager. The connection using MongoDB\Driver\Manager was successed but I couldn't anymore :(

My PHP version is 5.6.29. Mongo extension version is 1.7.0 MongoDB extension version is 1.2.9

My questions are: Do I have to use MongoDB\Driver\Manager Class? Is it better than MongoClient Class?

Answer 1

Here is a good answer about deprecated language features: What does PHP do with deprecated functions?

And here is a proper usage for php with mongodb:

$manager = new MongoDB\Driver\Manager("mongodb://localhost:27017");
$filter = [];
$options = [
    'sort' => ['_id' => 1],
];

$query = new MongoDB\Driver\Query($filter, $options);
$cursor = $manager->executeQuery('db.collection', $query);

foreach ($cursor as $document) {
//...
}

There are are a lot of tutorials for CRUD operation with php and mongodb, for example: MongoDB PHP tutorial

In short: you should not use deprecated feature because of security reasons and because it could get removed from php in the future. So better update your code.
