need to set the region if you aren’t using US East Region

Took a little while to get this working cos I’m not a developer.. so here are a few tips to get the SDK working

This needs version 1 of the AWS SDK for PHP
http://aws.amazon.com/sdkforphp/

As stated, you punch in your AWS credentials into a file called config.inc.php
Good idea to test the sdk with the sample script that comes with the SDK called “cli-s3_get_urls_for_uploads.php”

If you are behind a proxy, you can specify the proxy in sdk.class.php in the line “public proxy = ”
eg., public $proxy = “http://username:password@proxy:8080”;

Nb. I hit errors with proxies until I found out that proxy support was fixed in a recent commit:
https://github.com/amazonwebservices/aws-sdk-for-php/pull/49#commits-pushed-eb922ad

The AWS SDK for PHP defaults to the US East Region. (ec2.us-east-1.amazonaws.com)
You need to set the region if your instances are in a different region.
eg., if you were in Asia Pacific Singapore region..

Add a line after “$ec2 = new AmazonEC2();”
$ec2->set_hostname(‘ec2.ap-southeast-1.amazonaws.com’);

For a list of hosts and for the regions, refer to this…
