PHP Wrapper for the Google's Cayley graph database REST interface.
PHP Wrapper for the Google's Cayley graph database REST interface., (*1)
Cayley is an open-source graph inspired by the graph database behind Freebase and Google's Knowledge Graph. Its goal is to be a part of the developer's toolbox where Linked Data and graph-shaped data (semantic webs, social networks, etc) in general are concerned., (*2)
The Cayley's default query language is called Gremlin based on JavaScript. php-cayley is a replica of this Gremlin Javascript API in PHP, all the methods and patterns from Gremlin are applicable to this library., (*3)
The recommended way to install php-cayley is through composer. You can see the package information on Packagist., (*4)
{
"require": {
"mcuadros/php-cayley": "dev-master"
}
}
$cayley = new Cayley\Client();
$query = $cayley->graph()->vertex('Humphrey Bogart')->all();
$result = $cayley->query($query);
print_r($result);
$cayley = new Cayley\Client();
$filmToActor = $cayley->graph()
->morphism()
->out('/film/film/starring')
->out('/film/performance/actor');
$query = $cayley->graph()
->vertex()
->has('name', 'Casablanca')
->follow($filmToActor)
->out('name')
->all();
$starring = $cayley->query($query);
foreach($starring as $actor) {
var_dump($actor['id']);
}
These examples are based on the data contained in the example database 30kmoviedata.nq.gz, (*5)
For more information please read Gremlin Javascript API documentation., (*6)
Tests are in the tests folder.
To run them, you need PHPUnit.
Example:, (*7)
$ phpunit --configuration phpunit.xml.dist
