PhpOrient - Cluster Maps

When you open a database on the client interface, the return value is cluster map. This PHP class provides you with an interface and a series of methods for manipulating clusters on the database.

Using Clusters

In order to retrieve the cluster map for a database, you need to open the database and set the return value on a variable. For instance,

$clusterMap = $client->dbOpen("GratefulDeadConcerts", "admin", "admin);

You can then use the $clusterMap object in calling additional methods.

Method Description
count() Returns a count of records in the cluster.
dropClusterID() Removes a cluster from the database.
getIdList() Retrieves a list of Cluster ID's.


In cases where you want to know how many records the Cluster Map contains, you can obtains this using the count() method. For instance, you might want to test that a database contains records after opening it:

// Open Database
$clusterMap = $client->dbOpen("GratefulDeadConcerts", "admin", "admin);

// Report Count
$entityCount = $clusterMap->count();
echo "Database Contains: $entityCount records";
