If you are a PHP developer, this guide provides an overview of options for connecting to Neo4j. While this guide is not comprehensive it will introduce the different drivers and link to the relevant resources.
You should be familiar with graph database concepts and the property graph model. You should have installed Neo4j and made yourself familiar with our Cypher Query language.
Neo4j for PHP Developers
You’re a PHP developer and want to start with Neo4j? You’re in the right place!
Whether you’re using frameworks like Symfony and Laravel or you’re developing without frameworks, you’ll find an adequate library for your use case.
If you have any questions, you can always find a community member around on Twitter or StackOverflow by tagging your subjects with #neo4j-php.
Members of the PHP community have invested a lot of time and love to develop all these drivers, so please if you use them, provide feedback to the authors.
The Example Project
It is a small one page webapp for our movies database. The front-end is the same for all drivers, just the backends show you how to connect to Neo4j from the different languages and drivers.
Using Neo4j in a standalone PHP environment
If you prefer to develop without frameworks, these libraries are made for you:
Neo4jPHP provides an API that is both intuitive and flexible, and it takes advantage of ‘under-the-hood’ performance enhancements, such as caching and lazy-loading.
NeoClient is a powerful and flexible PHP Client for Neo4j with MultiDB support, and full High-Availability support for Neo4j Enterprise, and a convenient object formatter for handling graph results. It is built on top of the Symfony components, which makes integrating it in a modern PHP framework very easy. The 2.0 stable release has been announced end of November 14, with the following changes and improvements:
- Everything is built as an extension, meaning the core commands are an extension to the library, which makes the library very flexible and customizable.
- All commands are registered as lazy services, improving the library performance.
- The Service Container can be cached, gaining up to 300% performance when runnning in production.
- Full High-Availability support, with master re-election detection, slaves fallback built-in mechanism, and convenience methods for directing write and read queries to different databases.
- Minimalistic HA mechanism when running Neo4j Community Edition
- Full-fledged Response Graph format.
This library provides a basic Object-Graph mapping system and is built on top of Doctrine and the Neo4jPHP library.
With the Symfony framework
If you’re using the Symfony framework, these bundles are available to you:
This bundle is wraps the Neo4j-PHP-OGM library mentioned above.
NeoEloquent for Laravel
Neo4j Graph Eloquent Driver for Laravel 4
This is a PHP Data Objects driver for the Neo4j graph database, it allows you to connect to a Neo4j server from PHP using the standard PDO API. The project currently only implements a “vanilla” PHP implementation, which means you need to use a special constructor to create your PDO connection. PHP extensions to register the driver with PDO in HHVM and Zend VM are planned future work.
