<!--
Setup to connect to AWS S3 in PHP

1. Install Composer:
    Using Composer is the recommended way to install the AWS SDK for PHP.

    curl -sS https://getcomposer.org/installer | php


2. Run the Composer command to install the latest stable version of the SDK:

    php composer.phar require aws/aws-sdk-php


3. Require Composer's autoloader in your php file:

    require 'vendor/autoload.php';

4. Set environment variables for AWS Id and Key:

    export AWS_ACCESS_KEY_ID="YOUR_ACCESS_ID"
    export AWS_SECRET_ACCESS_KEY="YOUR_ACCESS_KEY"

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

// Use the us-west-2 region and latest version of each client.
$sharedConfig = [
    'region'  => 'us-west-2',
    'version' => 'latest'
];

// Create an SDK class used to share configuration across clients.
$sdk = new Aws\Sdk($sharedConfig);

// Use an Aws\Sdk class to create the S3Client object.
$s3Client = $sdk->createS3();

// Use an Aws\Sdk class to create the S3Client object.
$s3 = $sdk->createS3();

// using promises for asyncronous requests
$promise = $s3Client->listBucketsAsync();
$promise

    })
    ->otherwise(function ($reason) {
        echo 'Encountered an error: ' . $reason->getMessage();
    });

// Send a PutObject request and get the result object.
$result = $s3Client->putObject([
    'Bucket' => 'my-bucket',
    'Key'    => 'my-key',
    'Body'   => 'this is the body!'
]);

// Print the body of the result by indexing into the result object.
echo $result['Body'];

// Download the contents of the object.
$result = $s3Client->getObject([
    'Bucket' => 'my-bucket',
    'Key'    => 'my-key'

// Print the body of the result by indexing into the result object.
