amazon web services – Extract Protected Request Response from AWS SDK for PHP

Posted by: admin July 12, 2020 Leave a comment


I’m working with the new Amazon ElasticTranscoder service, and am new to working with the AWS-SDK. I have a successful script created that runs a createJob request, transcoding an Amazon S3 file from one format to another.

The problem is, I can’t seem to access the response $data that is returned when the request is made. I can see it, and it contains the information I need, but I receive this error when I attempted to store it:

Fatal error: Cannot access protected property Guzzle\Service\Resource\Model::$data

Here’s what my request looks like:

// Include the SDK
require 'aws.phar';
use Aws\ElasticTranscoder\ElasticTranscoderClient;

// Setup the trancoding service tool(s)
$client = ElasticTranscoderClient::factory( array(
    'key' => 'XXXXXXXXX',
    'secret' => 'XXXXXXXXX',
    'region' => 'us-east-1'
) );

// Create a new transcoding job
$file_name = '1362761118382-lqg0CvC1Z1.mov';
$file_name_explode = explode( '.', $file_name );

$webm_transcode_request = $client->createJob( array(
    'PipelineId' => '1362759955061-7ad779',
    'Input' => array(
        'Key' => $file_name,
        'FrameRate' => 'auto',
        'Resolution' => 'auto',
        'AspectRatio' => 'auto',
        'Interlaced' => 'auto',
        'Container' => 'auto',
    'Output' => array(
        'Key' => $file_name_explode[0] . '.webm',
        'ThumbnailPattern' => $file_name_explode[0] . '-thumb-{resolution}-{count}',
        'Rotate' => '0',
        'PresetId' => '1363008701532-b7d529' // BenchFly MP4
) );

// Print the response data
echo '<pre>';
var_dump( $webm_transcode_request->data );
echo '</pre>';

I’ve been banging my head against the wall trying to find some documentation on handling response requests with PHP and the AWS SDK, any help is very much appreciated.

How to&Answers:

You have two options:

  1. Use the toArray() method, listed under “Methods inherited from Guzzle\Common\Collection” in the docs.


  2. Just directly access indexes of the $data property as if they were indexes of the response object. This works because the Guzzle\Service\Resource\Model class implements PHP’s magic ArrayAccess interface to make array-like access operate on the $data property.


    $response = $ec2Client->describeInstances();
    // Gets the value of the 'Reservations' key of the protected `$data` property
    // of `$response`
