Neo4j PDO

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.

Installation

Neo4jPDO uses Composer, please checkout the composer website for more information.

To use Neo4j/PDO in your project, simply add it as a composer dependency:

"require": {
    "neo4j/pdo": "dev-master"
}

Minimum Viable Snippet

// Include dependencies installed with composer
require 'vendor/autoload.php';

$conn = new \Neo4j\Neo4jPDO("http://localhost:7474");

foreach($conn->query('MATCH (n) RETURN count(*) as count') as $row) 
{
    echo $row['count'];
}

Please refer to the PDO documentation in the PHP manual for detailed documentation of the API.
