To install and connect to MongoDB with PHP, follow the steps below:

Step 1: Install MongoDB

• Download the MongoDB Community Server from the official website (https://www.mongodb.com/try/download/community) and choose the appropriate version for your operating system.
• Follow the installation instructions specific to your operating system.
• Make sure that MongoDB is running by starting the MongoDB service or running the MongoDB server.

Step 2: Install MongoDB PHP Driver

• Open the terminal or command prompt and run the following command to install the MongoDB PHP driver: pecl install mongodb
• Once the installation is completed, add the following line to your PHP configuration file (php.ini): extension=mongodb.so
• Restart your web server or PHP service to load the new extension.

Step 3: Create a PHP Script

• Create a new PHP file, for example, connect.php.
• Use the following code as a basic example to connect to the MongoDB server and query the database:

<?php
// MongoDB connection string
$connection_string = 'mongodb://localhost:27017';

// Connect to MongoDB
$mongo_client = new MongoDBClient($connection_string);

// Select the database
$database = $mongo_client->my_database;

// Select the collection
$collection = $database->my_collection;

// Query the collection
$result = $collection->find();

// Loop through the resultset
foreach ($result as $document) {
    echo $document['_id'], ": ", $document['field'], "<br>";
}
?>

Make sure to update the connection string, database name, and collection name to fit your environment.

Step 4: Test the Connection

• Save the script and open it in your web browser. If everything is set up correctly, you should see the results printed on the page.

That's it! You have successfully installed MongoDB and connected to it using PHP. You can now perform various database operations using MongoDB's PHP library.

Just to clarify, in step 3, you need to use the correct class name for creating the MongoDB client object. The correct class name should be MongoDBClient. Here's the updated code snippet for step 3:

$connection_string = 'mongodb://localhost:27017';

// Connect to MongoDB
$mongo_client = new MongoDBClient($connection_string);

// Select the database
$database = $mongo_client->my_database;

// Select the collection
$collection = $database->my_collection;

// Query the collection
$result = $collection->find();

// Loop through the resultset
foreach ($result as $document) {
    echo $document['_id'], ": ", $document['field'], "<br>";
}
?>

Additionally, make sure to replace "my_database" and "my_collection" with the correct names of your database and collection respectively.
