Can't pass my credentials to AWS PHP SDK

Question

I installed AWS PHP SDK and am trying to use SES. My problem is that it's (apparently) trying to read ~/.aws/credentials no matter what I do. I currently have this code:

$S3_AK = getenv('S3_AK');
$S3_PK = getenv('S3_PK');
$profile = 'default';
$path = '/home/franco/public/site/default.ini';
$provider = CredentialProvider::ini($profile, $path);
$provider = CredentialProvider::memoize($provider);
$client = SesClient::factory(array(
      'profile' => 'default',
      'region' => 'us-east-1',
      'version' => "2010-12-01",
      'credentials' => [
        'key'    => $S3_AK,
        'secret' => $S3_PK,
      ]
  )); 

And am still getting "Cannot read credentials from ~/.aws/credentials" error (after quite a while).

I tried 'credentials' => $provider of course, that was the idea, but as it wasn't working I reverted to hardcoded credentials. I've dumped $S3_AK and $S3_PK and they're fine, I'm actually using them correctly for S3, but there I have Zend's wrapper. I've tried ~/.aws/credentials (no ".ini") to the same result. Both files having 777 permissions.

Curious information: I had to set memory limit to -1 so it would be able to var_dump the exception. The html to the exception is around 200mb.

I'd prefer to use the environment variables, all though the credentials file is fine. I just don't understand why it appears to be trying to read the file even though I've hardcoded the credentials.

EDIT: So a friend showed me this, I removed the profile and also modified the try/catch and noticed the client seems to be created properly, and the error comes from trying to actually send an email.

The trick is just remove 'profile' => 'default' from the factory params, if this is defined we can't use a custom credentials file or environment variables. Is not documented but just works.

I'm using Sns and Sdk v3.

<?php
use Aws\Credentials\CredentialProvider;

$profile = 'sns-reminders';
$path = '../private/credentials';

$provider = CredentialProvider::ini($profile, $path);
$provider = CredentialProvider::memoize($provider);

$sdk = new Aws\Sdk(['credentials' => $provider]);

$sns = $sdk->createSns([
//        'profile' => $profile,
        'region'  => 'us-east-1',
        'version' => 'latest',
]);
