AwsDynamoDbDynamoDbClientIteratorItemIterator.AwsDynamoDbDynamoDbClientModelAttribute.AwsDynamoDbDynamoDbClient::formatAttributes().AwsDynamoDbDynamoDbClient::formatValue().The new data types are a great addition to the Amazon DynamoDB service, but one consequence of adding support for these types is that we had to deprecate the following classes and methods in the AwsDynamoDb namespace of the PHP SDK: We are working on some ideas that will provide more help with these types in Version 3 of the SDK. This is because they are ambiguous with the string ( S) and list ( L) types and have no equivalent type in JSON. $data = $marshaler->unmarshalItem($result) īe aware that marshalItem() does not support binary ( B) and set ( SS, NS, and BS) types. Getting and item and unmarshaling the data. Marshaling the data and putting an item. This is essentially an upgraded version of the existing DynamoDbClient::formatAttributes() method. The Marshaler also provides the marshalItem() and unmarshalItem() methods that do the same type of thing, but for arrays. $json = $marshaler->unmarshalJson($result) To retrieve an item and get the JSON document back, you need to use the unmarshalJson() method. The output of marshalJson() is an associative array that includes all the type information required for the DynamoDB 'Item' parameter. $json = file_get_contents('/path/to/your/document.json') $client = DynamoDbClient::factory(/* your config */) You can use the DynamoDB Marshaler to convert this JSON document into the format required by DynamoDB. Let’s say you have JSON document describing a contact in the following format: The Marshaler object has methods for marshaling JSON documents and PHP arrays to the DynamoDB item format and unmarshaling them back.

To make these new types even easier for our PHP SDK users, we added a new class, called the DynamoDB Marshaler, in Version 2.7.7 of the AWS SDK for PHP. These new types, along with some API updates, make it possible to store more complex, multilevel data, and use DynamoDB for document storage. Back in October of 2014, Amazon DynamoDB added support for new data types, including the map ( M) and list ( L) types.
