PHP Fatal error: Uncaught Error: Class 'Aws\Common\Aws' not found in test.php

Question

I installed AWS PHP SDK v3 based on http://docs.aws.amazon.com/aws-sdk-php/v3/guide/getting-started/installation.html using composer method. Tried a simple example but getting this error:

PHP Fatal error:  Uncaught Error: Class 'Aws\Common\Aws' not found in test.php

Code:

<?php

// Include the SDK using the Composer autoloader
require 'vendor/autoload.php';

use Aws\Common\Aws;

$aws = Aws::factory('./cfg.php');

/* CODE BELOW WORKS FINE BY ITSELF
$s3 = new Aws\S3\S3Client([
    'version' => 'latest',
    'region'  => 'us-west-1',
    'credentials' => [
        'key'    => '***',
        'secret' => '***'
    ],
]);

$result = $s3->listBuckets();

foreach ($result['Buckets'] as $bucket) {
    // Each Bucket value will contain a Name and CreationDate
    echo "{$bucket['Name']} - {$bucket['CreationDate']}\n";
}
*/
?>

My PHP version:

PHP 7.1.0alpha2 (cli) (built: Jun 27 2016 22:39:02) ( NTS )
Copyright (c) 1997-2016 The PHP Group
Zend Engine v3.1.0-dev, Copyright (c) 1998-2016 Zend Technologies

I tried including aws.phar instead but still did not work.

Not sure what ./cfg.php contains, but if you follow your commented code.

You could use Aws\\Kms\\KmsClient and do something like:

require 'vendor/autoload.php';

$client = Aws\Kms\KmsClient::factory(/*Config Array or Guzzle Http Client*/);

$result = $client->listKeys();

Just so you know, Aws\\Kms\\KmsClient is nearly the exact same client as Aws\\AwsClient

Further info on that config needed to create the client
