How to upload a folder into AWS

Iam using AWS to upload images, css and some zip files for my site and they are fine to upload them.But now I want like I first upload a zip on localhost and I will extract them into one folder and I want to upload that entire folder into aws.Can anyone help me to do it.Thanks in advance.

Iam using function to upload files like

require_once 'aws-sdk-for-php/sdk.class.php';
$s3 = new AmazonS3();
$response = $s3->create_object($bucket, $filename, array(
'fileUpload' => $filepath,
 'acl' => AmazonS3::ACL_PUBLIC,
'storage' => AmazonS3::STORAGE_REDUCED,
'headers' => array(
    'Cache-Control'    => 'max-age=2592000'
);

It is working fine for single images.But I dont know how to do it for entore folder.
