How to authenticate to MongoDB using PHP?

Step 1: Install MongoDB PHP extension

Before connecting to MongoDB from PHP, you need to install the MongoDB PHP extension. You can use the following command to install it using composer:

1

composer require mongodb/mongodb

You can also download the extension from the official website and install it manually.

Step 2: Create a MongoDB connection object

To connect to a MongoDB server, you need to create a connection object. You can use the following code to create a MongoDB connection object:

1

$client = new MongoDBClient("mongodb://localhost:27017");

Here, mongodb://localhost:27017 is the connection string of the MongoDB server. Replace localhost with the IP address or hostname of the server where MongoDB is installed.

Step 3: Authenticate to MongoDB

If your MongoDB deployment requires authentication, you need to provide the credentials when connecting to the server. You can use the following code to authenticate to MongoDB from PHP:

1

$client = new MongoDBClient("mongodb://username:password@localhost:27017");

Here, username and password are the MongoDB user credentials. Replace localhost with the IP address or hostname of the server where MongoDB is installed.

Step 4: Select the MongoDB database

Once you have connected to MongoDB, you need to select the database that you want to work with. You can use the following code to select a database:

1

$collection = $client->selectCollection("dbname", "collectionname");

Replace dbname with the name of the database you want to use, and collectionname with the name of the collection you want to work with.

Step 5: Perform MongoDB operations

Now that you have authenticated to MongoDB and selected a database, you can perform various MongoDB operations using the MongoDB PHP driver. Here's an example:

$result = $collection->insertOne([
    'name' => 'John Doe',
    'email' => '[email protected]',
    'phone' => '1234567890'
]);

echo $result->getInsertedCount();

This code inserts a new document into the selected collection and returns the number of documents inserted. You can perform various other operations such as find, update, and delete using the MongoDB PHP driver.
