Connect to MongoDB

After retrieving the connection string for your MongoDB Atlas deployment, you can connect to the deployment from your PHP application and query the Atlas sample datasets.

1

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;
$client = new Client('<connection string>');
$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";
}
2

Assign the connection string

Replace the <connection string> placeholder with the connection string that you copied from the Create a Connection String step of this guide.

3

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 specified the proper connection string in the quickstart.php file and that you loaded the sample data.

After you complete these steps, you have a PHP application that connects to your MongoDB deployment, runs a query on the sample data, and returns a matching document.

Note

If you run into issues on this step, ask for help in the MongoDB Community Forums or submit feedback by using the Rate this page tab on the right or bottom right side of this page.
