Requirements

• A GrapheneDB account, you can create one here : https://app.graphenedb.com/signup

You need to pass a name for your database, and optionally a neo4j version :

$myNewDB = $client->createDatabase('test');

By default, the latest neo4j version will be used (currently 2.1.5)

This will return you a Neoxygen\GrapheneDBClient\Database instance, for the available methods of this class read the section The Database class.

$client->getVersions();

Array
(
    [default] => v215
    [versions] => Array
        (
            [0] => Array
                (
                    [version] => v198
                    [label] => Neo4j Community Edition 1.9.8
                )

                    [label] => Neo4j Community Edition 2.1.5
                )

        )
