Require the package in your dependencies :
composer require graphaware/neo4j-bolt
use GraphAware\Bolt\GraphDatabase;
$driver = GraphDatabase::driver("bolt:https://localhost");
$session = $driver->session();
$session = $driver->session();
$session->run("CREATE (n)");
$session->close();
// with parameters :
$session->run("CREATE (n) SET n += {props}", ['name' => 'Mike', 'age' => 27]);
Due to lack of Collections types in php, there is no way to distinguish when an empty array should be treated as equivalent Java List or Map types.
Therefore you can use a wrapper around arrays for type safety :
use GraphAware\Common\Collections;
$query = 'MERGE (n:User {id: {id} })
WITH n
UNWIND {friends} AS friend
MERGE (f:User {id: friend.name})
MERGE (f)-[:KNOWS]->(n)';
$params = ['id' => 'me', 'friends' => Collections::asList([])];
$this->getSession()->run($query, $params);
// Or
$query = 'MERGE (n:User {id: {id} })
WITH n
UNWIND {friends}.users AS friend
MERGE (f:User {id: friend.name})
MERGE (f)-[:KNOWS]->(n)';
$params = ['id' => 'me', 'friends' => Collections::asMap([])];
$this->getSession()->run($query, $params);
In order to enable TLS support, you need to set the configuration option to REQUIRED
, here an example :
$config = \GraphAware\Bolt\Configuration::newInstance()
->withCredentials('bolttest', 'L7n7SfTSj0e6U')
->withTLSMode(\GraphAware\Bolt\Configuration::TLSMODE_REQUIRED);
$driver = \GraphAware\Bolt\GraphDatabase::driver('bolt:https://hobomjfhocgbkeenl.dbs.graphenedb.com:24786', $config);
$session = $driver->session();
