AWSSDK - S3 - if_object_exists keeps returning a Argument 2 passed to Guzzle error

Question

I have a S3 bucket with 2million MP3 files inside of it and there are times when customers order a mp3 file but they are unable to download the file from our S3 bucket. Before I go and request a redelivery of the file from the content provider, I want to create a simple script that will allow me to check if the file exists in the S3 bucket. I've written a script to check the bucket, but it's I keep getting this error:

Catchable fatal error: Argument 2 passed to Guzzle\Service\Client::getCommand() must be an array, string given, called in phar:///mnt/universal_portal/prod/download/aws.phar/vendor/guzzle/guzzle/src/Guzzle/Service/Client.php on line 93 and defined in phar:///mnt/universal_portal/prod/download/aws.phar/vendor/guzzle/guzzle/src/Guzzle/Service/Client.php on line 113

This is the code I've written

require_once('appsettings.php');
require 'aws.phar';

use Aws\S3\S3Client;

$client = S3Client::factory(array(
   'key'    => $aws_key,
   'secret' => $aws_secret
));

$filename = '000002422704.mp3' . strtolower($aws_key);
$info = $client->if_object_exists($aws_bucket,$filename);

return $info;

I've been going off this Amazon link, but I can't get this file check to work.

Any help is greatly appreciated.

Cheers

The link you posted is for SDK 1.x. The Phar file and the instantiation you're using is for SDK 2.x. They both need to be the same version. :)

You're looking for Aws\S3\S3Client::doesObjectExist() in SDK 2.x.
