difficulty initialising Amazon AWS php SDK - Class Aws\Common\Aws not found

Question

I'm trying to instantiate the Amazon AWS SDK PHP with the following code:

require("../aws/aws-autoloader.php");

use Aws\S3\S3Client;
use Aws\Common\Aws;


// Instantiate the client.

$aws = Aws::factory('awsConfig.php');
$s3Client = $aws->get('s3');

I'm however getting returned the following error:

Uncaught Error: Class 'Aws\Common\Aws' not found

The aws-autoloader file has not been modified from the source so not entirely sure why it's not finding the class?

Answer 1

You're using AWS SDK for PHP v3, while trying to execute code for AWS SDK for PHP v2. You should use Aws\Sdk instead of Aws\Common\Aws.

AWS provides a migration guide highlighting the differences between version 2 and version 3:

From Version 3 of the SDK

Key differences:

Use the Aws\Sdk class instead of Aws\Common\Aws.

No configuration file. Use an array for configuration instead.

The 'version' option is required during instantiation.

Use the create() methods instead of get('').
