Connecting Neo4j server with Neo4jPHP gives 401

Question

We are just installing our first Neo4j 2.1 application to Jelastic server environment and can't get connection to db working. The simple program (from an answer in neo4jphp: Cannot instantiate abstract class Everyman\Neo4j\Transport) is this:

require('vendor/autoload.php');

use Everyman\Neo4j\Client;
$client = new Client($Server_ip_address, 8080);
print_r($client->getServerInfo());

The last row gives an error 401 Unauthorized:

'Unable to retrieve server info [401]:\nHeaders: Array
(
[WWW-Authenticate] => Basic realm="neo4j graphdb"
[Content-Type] => text/html; charset=ISO-8859-1
[Cache-Control] => must-revalidate,no-cache,no-store
[Content-Length] => 0
[Server] => Jetty(9.0.5.v20130815)
)
Body: Array
(
)
'.

Should I configure the user_id/password somewhere in my Apache 2.2 environment, or is there something else missing?

Thanks after all! The working version is this:

require('vendor/autoload.php');   
use Everyman\Neo4j\Client;
$client = new Everyman\Neo4j\Client($host, $port);
$client->getTransport()
  ->setAuth($username, $password);
print_r($client->getServerInfo());

Also "->useHttps()" should be used, if you don't have a trusted environment.

I have found no examples how credentials should be given, normally they are not expressed. The documents in http://jadell.github.io/neo4jphp/docs/index.html tell that there is a function Transport.setAuth($user, $passwd), but it is not good idea to hard code these. Is there any other ways to set the credentials in for example php.ini? — Juha M, Feb 12 '15 at 19:51
I tried to use the setAuth method, but it fails: "Cannot instantiate abstract class Everyman\\Neo4j\\Transport". I wrote ` $client = new Client(new Transport('10.50.8.204', 8080).setAuth('admin', $mypasswd));` — Juha M, Feb 13 '15 at 02:27
You don't need to instantiate a new Transport. The `setAuth` method is called on the $client. You are correct that you should never hardcode security credentials into an application. You can store the username/password anywhere you normally store credentials to read into your application securely: config files, Apache environment vars, etc. — Josh Adell, Feb 13 '15 at 14:29

If you are using authentication, you need to pass along the username/password, as shown in the example at https://github.com/jadell/neo4jphp/wiki/Getting-started#testing-your-connection

require('vendor/autoload.php');

use Everyman\Neo4j\Client;
$client = new Client($Server_ip_address, 8080);
$client->setAuth($username, $password);
print_r($client->getServerInfo());

Additionally, if you are using HTTPS (recommended if you are using authentication) you should also do:

$client->useHttps();
