什么像tinkerpop的PHP？

Question

I am just getting started with graph databases. I would like to talk to them in a PHP application. In particular, I am looking at OrientDB, mainly because of its licensing benefits and features over neo4j.

What is the recommended way to interact with OrientDB within PHP? Is there a generalized framework like tinkerpop for the PHP world?

I would like to query my graphs using mainly gremlin and a bit of OrientDB's extended SQL (only if necessary).

I know there are 2 php connectors: Orient and OrientDB-PHP, but have not tried them yet. Has anyone had any experiences with them? What are the pros and cons? I would of course prefer something like tinkerpop for PHP if it exists, but if it doesn't a library geared towards OrientDB is fine too.

I'm Alex, I actually wrote the biggest part of the codebase for Orient (the php library).

In PHP, currently, there is no thing like tinkerpop but I think you should be able to kickstart with Orient. Using it its extremely simple:

<?php

namespace Congow\Orient;

use Congow\Orient\Binding\HttpBinding;
use Congow\Orient\Binding\BindingParameters;

require __DIR__.'/../autoload.php';

$parameters = BindingParameters::create('http://admin:admin@127.0.0.1:2480/friends');
$binding = new HttpBinding($parameters);

$response = $binding->query('select from friends where any() traverse(0,1) ( @rid = #5:3 ) and @rid <> #5:3');
$friends = $response->getResult();

foreach ($friends as $friend) {
    echo $friend->name, "
";
}

Instead of writing the query from scratch you can also use the query builder:

$query = new Select(array('myClass'));
$query->orderBy("name ASC", false);

echo $query->getRaw() // SELECT FROM myClass ORDER BY name ASC

You could have a look at the tests of the library, or at the mini-samples in the example directory.

We are slowly keep going on with the development, so you find a few resources here: http://odino.org/blog/categories/orientdb/
