Keep in mind this code, to compare with next API
2. Second API is Neurofuzzy API. I don't used it never, check it here.
3. And finally last API - Tarzan. Tarzan is for all AWS Services. It is big library, flexible and simple. Here is the sample code, which is do same what do first code.
Click here to show sample Tarzan AWS code

<code><?php
require_once('tarzan.class.php');

/**
* Instantiate a new AmazonS3 object using the settings from the config.inc.php file.
*/
$s3 = new AmazonS3();

/**
* Store a remote file in S3.
*/
$file_url = $s3->store_remote_file('http://yahoo.com', 'warpshare.test.eu', 'yahoo_home.html', array(
'acl' => S3_ACL_PUBLIC
));

/**
* Display the new S3 URL for the stored file. (http://warpshare.test.eu.s3.amazonaws.com/yahoo_home.html)
