/**
* PHP Server-Side Example for Fine Uploader S3.
* Maintained by Widen Enterprises.
*
* Note: This is the exact server-side code used by the S3 example
* on fineuploader.com.
*
* This example:
* - handles both CORS and non-CORS environments
* - handles delete file requests for both DELETE and POST methods
* - Performs basic inspections on the policy documents and REST headers before signing them
* - Ensures again the file size does not exceed the max (after file is in S3)
* - signs policy documents (simple uploads) and REST requests
* (chunked/multipart uploads)
*
* Requirements:
* - PHP 5.3 or newer
* - Amazon PHP SDK (only if utilizing the AWS SDK for deleting files or otherwise examining them)
*
* If you need to install the AWS SDK, see http://docs.aws.amazon.com/aws-sdk-php-2/guide/latest/installation.html.
