I'm Alberto, one of the founders of GrapheneDB. I'd like to help you sort out your connection issues.

Have you made sure you have installed Neo4jPHP correctly using composer? You should run $ composer update after updating the composer.json file to update your dependencies.

Neo4jPHP is not currently not actively maintained so even if that works, I'd encourage you to use Neoxygen Neoclient instead. These are the necessary steps:

Include the dependency in composer.json:

{
    "require": {
        "neoxygen/neoclient": "~2.0"
    }
}

Update your dependencies

$ composer update

Require the library and configure the connection:

<?php

require_once 'vendor/autoload.php';

use Neoxygen\NeoClient\ClientBuilder;

$url = parse_url(getenv('GRAPHENEDB_URL'));

$client = ClientBuilder::create()
    ->addConnection('default', $url['scheme'], $url['host'], $url['port'], true, $url['user'], $url['pass'])
    ->setAutoFormatResponse(true)
    ->build();

Hope this helps.
