Reference documentation and code samples for the Cloud Datastore Client class Entity.
A Datastore Entity
Entity implements PHP's ArrayAccess , allowing
access via the array syntax (example below).
Properties are mapped automatically to their corresponding Datastore value
types. Refer to the table below for a guide to how types are stored.
Example:
use Google\Cloud\Datastore\DatastoreClient;
$datastore = new DatastoreClient();
$key = $datastore->key('Person', 'Bob');
$entity = $datastore->entity($key, [
'firstName' => 'Bob',
'lastName' => 'Testguy'
]);
$firstName = $entity['firstName']; // 'Bob'
$entity['location'] = 'Detroit, MI';
// Custom entity types can be created by implementing the datastore entity interface.
// You can also define mappings to correctly fetch embedded entities.
use Google\Cloud\Datastore\EntityTrait;
use Google\Cloud\Datastore\EntityInterface;
class Business implements EntityInterface
{
use EntityTrait;
public static function mappings()
{
return [
'parent' => Business::class
];
}
}
$alphabet = new Business;
$alphabet->set([
'companyName' => 'Alphabet'
]);
$key = $datastore->key('Business', 'Google');
$google = $datastore->entity($key, [
'companyName' => 'Google',
'parent' => $alphabet
], [
'className' => Business::class
]);
$datastore->insert($google);
$google = $datastore->lookup($key, ['className' => Business::class]);
echo get_class($google); // `Business`
echo get_class($google->get()['parent']); // `Business`
