How can i use existing S3Client

I’m using some php functions to carry out other operations (unrelated to Offload functions) on files in my bucket for which I need an $s3Client instance.
I can’t work out how to use Offload’s existing client connection rather than creating a new client myself – this is my working code:

$MyCreds = unserialize(AS3CF_SETTINGS); // Defined in wp-config.php

$provider = $MyCreds[‘provider’];
$key = $MyCreds[‘access-key-id’];
$secret = $MyCreds[‘secret-access-key’];

//Create a S3Client
$s3Client = new Aws\S3\S3Client([
‘version’ => ‘latest’,
‘region’ => ‘eu-west-2’
]);

$s3 = $s3Client::factory(array(
‘version’ => ‘latest’,
‘region’ => ‘eu-west-2’,
‘credentials’ => array(
‘provider’ => $provider,
‘key’ => $key,
‘secret’ => $secret
)
));

$result = $s3->listBuckets();

foreach ($result[‘Buckets’] as $bucket)
{
echo $bucket[‘Name’] . ‘<br>’;
}

Obviously, it would be nice if I could use the existing connection.

I’ve been trying stuff like:

$s3 = $as3cf->get_s3client;

But just can’t figure it out.

Any help much appreciated.

Thanks.
