MongoDB PHP Library

Overview

Welcome to the documentation site for the official MongoDB PHP Library.

The PHP library provides a high-level abstraction around the lower-level mongodb extension.

The mongodb extension provides a limited API to connect to a MongoDB database and execute generic commands, queries, and write operations. In contrast, the PHP library provides a full-featured API and models client, database, and collection objects. If you are developing a PHP application with MongoDB, consider using the PHP library instead of the extension alone.
