title: difficulty initialising Amazon AWS php SDK - Class Aws\Common\Aws not found
body: <p>I'm trying to instantiate the Amazon AWS SDK PHP with the following code:</p>
  
  <pre><code>require("../aws/aws-autoloader.php");
  
  use Aws\S3\S3Client;
  use Aws\Common\Aws;
  
  
  // Instantiate the client.
  
  $aws = Aws::factory('awsConfig.php');
  $s3Client = $aws-&gt;get('s3');
  </code></pre>
  
  <p>I'm however getting returned the following error:</p>
  
  <blockquote>
    <p>Uncaught Error: Class 'Aws\Common\Aws' not found</p>
  </blockquote>
  
  <p>The aws-autoloader file has not been modified from the source so not entirely sure why it's not finding the class?</p>
