Welcome to the documentation site for the official MongoDB PHP driver. You can add the driver to your application to work with MongoDB in PHP. The MongoDB PHP Driver consists of the following components:

  • The extension, which provides a low-level API and mainly serves to integrate libmongoc and libbson with PHP.

  • The library, which provides a high-level API for working with MongoDB databases consistent with other MongoDB language drivers.

While it is possible to use the extension alone, MongoDB recommends using both the extension and the library together. To learn more about the components of the PHP driver, see the Driver Architecture section of this page.

Navigate through the following links to learn more about the driver and access tutorial content on setting up a runnable project:

This section describes how the components of the PHP driver work together. These components fit into the following general categories:

  • High-Level API, which includes the library and other integrations

  • Extension, which includes the extension that integrates the system libraries

  • System, which includes the C Driver, BSON library, and encryption library

The following diagram illustrates the architecture of the PHP driver components:

PHP driver component architecture

The PHP library provides an API that is consistent with the other MongoDB drivers. The library is continually updated to meet cross-driver specifications. You must add the library as a dependency to access MongoDB in most PHP applications.

The extension is distributed by using PECL, and connects PHP to the system libraries. The extension's public API provides the following functionality:

  • Connection management

  • BSON encoding and decoding

  • Object document serialization

  • Command execution

  • Cursor management

To learn more about the system libraries, see the C Driver documentation.

You can use the PHP driver to connect to deployments hosted in the following environments:

  • MongoDB Atlas: The fully managed service for MongoDB deployments in the cloud

  • MongoDB Enterprise: The subscription-based, self-managed version of MongoDB

  • MongoDB Community: The source-available, free-to-use, and self-managed version of MongoDB

First, make sure you have a recent version of PHP installed on your system. See the official PHP manual for download and installation instructions.

Install the PHP MongoDB Extension before installing the PHP Library for MongoDB. You can install the extension using PECL on the command line:

$ sudo pecl install mongodb

Finally, add the following line to your php.ini file:

extension=mongodb.so

Note

On some systems, there may be multiple INI files for individual SAPIs (e.g. CLI, FPM). Make sure to enable the extension in all SAPIs that you need.

The preferred method of installing the PHP library is with Composer by running the following from your project root:

$ composer require mongodb/mongodb

Once you have installed the library, ensure that your application includes Composer's autoloader as in the following example:

<?php
require_once __DIR__ . '/vendor/autoload.php';

Additional installation instructions may be found in the library documentation.

You can use the following connection snippet to test your connection to your MongoDB deployment on Atlas:

<?php
use Exception;
use MongoDB\Client;
use MongoDB\Driver\ServerApi;
// Replace the placeholder with your Atlas connection string
$uri = '<connection string>';
// Specify Stable API version 1
$apiVersion = new ServerApi(ServerApi::V1);
// Create a new client and connect to the server
$client = new MongoDB\Client($uri, [], ['serverApi' => $apiVersion]);
try {
// Send a ping to confirm a successful connection
$client->selectDatabase('admin')->command(['ping' => 1]);
echo "Pinged your deployment. You successfully connected to MongoDB!\n";
} catch (Exception $e) {
printf($e->getMessage());
}

This connection snippet uses the Stable API feature, which you can enable when using the PHP driver v1.9 and later to connect to MongoDB Server v5.0 and later. When you use this feature, you can update your driver or server without worrying about backward compatibility issues with any commands covered by the Stable API.

To learn more about the Stable API feature, see Stable API in the Server manual.

Note

Starting from February 2022, the Versioned API is known as the Stable API. All concepts and features remain the same with this naming change.

If you are using a version of MongoDB or the driver that doesn't support the Stable API feature, you can use the following code snippet to test your connection to your MongoDB deployment on Atlas:

<?php
use Exception;
use MongoDB\Client;
// Replace the placeholder with your Atlas connection string
$uri = '<connection string>';
// Create a new client and connect to the server
$client = new MongoDB\Client($uri);
try {
// Send a ping to confirm a successful connection
$client->selectDatabase('admin')->command(['ping' => 1]);
echo "Pinged your deployment. You successfully connected to MongoDB!\n";
} catch (Exception $e) {
printf($e->getMessage());
}

If you need to run a MongoDB server on your local machine for development purposes instead of using an Atlas cluster, you need to complete the following:

  1. Download the Community or Enterprise version of MongoDB Server.

  2. Install and configure MongoDB Server.

  3. Start the server.

Important

Always secure your MongoDB server from malicious attacks. See our Security Checklist for a list of security recommendations.

After you successfully start your MongoDB server, specify your connection string in your driver connection code.

If your MongoDB Server is running locally, you can use the connection string "mongodb://localhost:<port>" where <port> is the port number you configured your server to listen for incoming connections.

If you need to specify a different hostname or IP address, see our Server Manual entry on Connection Strings.

To test whether you can connect to your server, replace the connection string in the Connect to MongoDB Atlas code example and run it.

Due to potential problems representing 64-bit integers on 32-bit platforms, users are advised to use 64-bit environments. When using a 32-bit platform, be aware that any 64-bit integer read from the database will be returned as a MongoDB\BSON\Int64 instance instead of a PHP integer type.

The following compatibility table specifies the recommended version or versions of the PHP driver for use with a specific version of MongoDB.

The first column lists the driver version.

Important

MongoDB ensures compatibility between the MongoDB Server and the drivers for three years after the server version's end of life (EOL) date. To learn more about the MongoDB release and EOL dates, see MongoDB Software Lifecycle Schedules.
