S3 client initialization error via PHP SDK

Question

I'm trying to initialize the S3 client from the AWS PHP SDK. My code is as follows:

$credentials = new Credentials(self::KEY, self::SECRET);

$s3_client = new S3Client([
    'version'     => 'latest',
    'region'      => $region,
    'credentials' => $credentials
]);

But am getting the following errors:

A PHP Error was encountered

Severity: 4096

Message: Argument 1 passed to Aws\\Common\\Client\\AbstractClient::__construct() must implement interface Aws\\Common\\Credentials\\CredentialsInterface, array given, called in /opt/showhouse/www/application/models/showhouse/common/services/aws/aws.php on line 47 and defined Filename: Client/AbstractClient.php

Line Number: 73

Any ideas where I am going wrong? Am using the latest version of the SDK installed via Composer.

Answer 1

I'm guessing you are using AWS PHP SDK version 2.0. If so, then the S3Client indeed implements the AbstractClient class. This means that the parameters are: __construct( Aws\\Common\\Aws\\Common\\Credentials\\CredentialsInterface $credentials, Aws\\Common\\Aws\\Common\\Signature\\SignatureInterface $signature, Guzzle\\Common\\Collection $config )

The S3Client implementation you are attempting to use is from version 3.0 of the AWS PHP SDK.

Recommendation: Try using a downloaded zip file to install AWS SDK instead of Composer

I had the same problem when I used Composer to install AWS SDK because it appeared to be the recommended way in AWS documentation from the following URL.

https://docs.aws.amazon.com/aws-sdk-php/v3/guide/getting-started/installation.html

But, after reading the helpful answer by Grilly, I decided to try using a downloaded zip file to install AWS SDK. The problem disappeared after I installed this way.

From a README file contained in the zip file, I could find a notification that the version of AWS SDK installed using the downloaded zip file was 3.0. Although I couldn't check version of AWS SDK installed using Composer because I couldn't find how, I am guessing that the version of AWS SDK installed using Composer was somewhat old enough to cause the problem.
