Reference documentation and code samples for the Cloud Datastore Client class DatastoreClient.
Google Cloud Datastore is a highly-scalable NoSQL database for your applications. Find more information at the Google Cloud Datastore docs.
Cloud Datastore supports multi-tenant applications through use of data partitions. A partition ID can be supplied when creating an instance of Cloud Datastore, and will be used in all operations executed in that instance.
To enable the
Google Cloud Datastore Emulator,
set the DATASTORE_EMULATOR_HOST
environment variable.
Example:
use Google\Cloud\Datastore\DatastoreClient;
$datastore = new DatastoreClient();
// Multi-tenant applications can supply a namespace ID.
use Google\Cloud\Datastore\DatastoreClient;
$datastore = new DatastoreClient([
'namespaceId' => 'my-application-namespace'
]);
// Using the Datastore Emulator
use Google\Cloud\Datastore\DatastoreClient;
// Be sure to use the port specified when starting the emulator.
// `8900` is used as an example only.
putenv('DATASTORE_EMULATOR_HOST=localhost:8900');
$datastore = new DatastoreClient();
// Multi-database applications can supply a database ID.
use Google\Cloud\Datastore\DatastoreClient;
$datastore = new DatastoreClient([
'namespaceId' => 'my-application-namespace',
'databaseId' => 'my-database'
]);

keys
Create multiple keys with the same configuration.
When inserting multiple entities, creating a set of keys at once can be useful. By defining the Key's kind and any ancestors up front, and allowing Cloud Datastore to allocate IDs, you can be sure that your entity identity and ancestry are correct and that there will be no collisions during the insert operation.
Example:
$keys = $datastore->keys('Person', [
'number' => 10
]);
// Ancestor paths can be specified
$keys = $datastore->keys('Person', [
'ancestors' => [
['kind' => 'Person', 'name' => 'Grandpa Joe'],
['kind' => 'Person', 'name' => 'Dad Mike']
],
'number' => 3
]);
Parameters | |

Name | Description |
kind |
string

↳ id |
string|int
The ID for the last pathElement. |
↳ name |
string
The Name for the last pathElement. |
Returns | |
---|---|
Type | Description |
array<Google\Cloud\Datastore\Key> |
entity
Create an entity.
This method does not execute any service requests.
Entities are created with a Datastore Key, or by specifying a Kind. Kinds are only allowed for insert operations. For any other case, you must specify a named key. If a kind is given, an ID will be automatically allocated for the entity upon insert. Additionally, if your entity requires a complex key elementPath, you must create the key separately.
In complex applications you may want to create your own entity types. Google Cloud PHP supports subclassing of Google\Cloud\Datastore\Google\Cloud\Datastore\Entity. If the name of a subclass of Entity is given in the options array, an entity will be created with that class rather than the default class.
Example:
$key = $datastore->key('Person', 'Bob');
$entity = $datastore->entity($key, [
'firstName' => 'Bob',
'lastName' => 'Testguy'
]);
// Entity values can be assigned and accessed via the array syntax.
$entity = $datastore->entity($key);
$entity['firstName'] = 'Bob';
$entity['lastName'] = 'Testguy';
// Entity values can also be assigned and accessed via an object syntax.
$entity = $datastore->entity($key);
$entity->firstName = 'Bob';
$entity->lastName = 'Testguy';
// Entities can be created with a Kind only, for inserting into datastore
$entity = $datastore->entity('Person');
// Entities can be custom classes implementing the Datastore entity interface.
use Google\Cloud\Datastore\EntityTrait;
use Google\Cloud\Datastore\EntityInterface;
class PersonEntity implements EntityInterface
{
use EntityTrait;
}
$person = $datastore->entity('Person', [ 'firstName' => 'Bob'], [
'className' => PersonEntity::class
]);
echo get_class($person); // `Person`
// Custom entity types may also extend the built-in Entity class.
use Google\Cloud\Datastore\Entity;
class OtherPersonEntity extends Entity
}
$person = $datastore->entity('Person', [ 'firstName' => 'Bob'], [
'className' => OtherPersonEntity::class
]);
echo get_class($person); // `Person`
// If you wish to exclude certain properties from datastore indexes,
// property names may be supplied in the method $options:
$entity = $datastore->entity('Person', [
'firstName' => 'Bob',
'dateOfBirth' => new DateTime('January 31, 1969')
], [
'excludeFromIndexes' => [
'dateOfBirth'
]
]);
