Getting an item from the DynamoDB table using the AWS SDK for PHP

Let's understand how to get an item from the DynamoDB table using the AWS SDK for PHP.

Getting ready

To perform this operation, you can use the IDE of your choice.

How to do it…

Let's try to understand how to retrieve a stored item from the DynamoDB table using PHP:

1. Create an instance of the DynamoDB client and initialize it with the AWS region and credentials:

   $client = DynamoDbClient::factory(array(
       'profile' => 'default',
       'region' => 'us-east-1'   
   ));

2. Call the getItem method by specifying the primary key used for the table:

   $response = $client->getItem(array(
       'TableName' => 'productTable',
       'Key' => array(
           'id' => array( 'N' => 30 ),'type' => array( 'S' => 'phone' )
       )
   ));

3. You can print the response if required:

   print_r ($response['Item']);

How it works…

The API invocations call the DynamoDB services and get the item from the specified table.
