Connect to MongoDB

Edit your PHP application file

Copy and paste the following code into the quickstart.php file, which queries the movies collection in the sample_mflix database:

<?php
require __DIR__ . '/../vendor/autoload.php';
use MongoDB\Client;
$uri = getenv('MONGODB_URI') ?: throw new RuntimeException(
    'Set the MONGODB_URI environment variable to your Atlas URI'
);
$client = new MongoDB\Client($uri);
$collection = $client->sample_mflix->movies;
$filter = ['title' => 'The Shawshank Redemption'];
$result = $collection->findOne($filter);
if ($result) {
    echo json_encode($result, JSON_PRETTY_PRINT);
} else {
    echo 'Document not found';
}

Assign the connection string

Assign the MONGODB_URI environment variable to the connection string that you copied from the Create a Connection String step of this guide. You can assign this variable by running a shell command or creating a .env file in your application, as show in the following tabs:

export MONGODB_URI=<connection string>

MONGODB_URI=<connection string>

Run your PHP application

In your project directory, run the following shell command to start the application:

php quickstart.php

The command line output contains details about the retrieved movie document:

{
    "_id": {
        "$oid": "..."
    },
    ...
   "rated": "R",
   "metacritic": 80,
   "title": "The Shawshank Redemption",
   ...
}

If you encounter an error or see no output, ensure that you assigned the proper connection string to the MONGODB_URI environment variable and that you loaded the sample data.
