PHP/Amazon S3: Query string authentication <p>I have been using the <code>Zend_Service_Amazon_S3</code> library to access Amazon S3, but have been unable to find anything that correctly deals with generating the secure access URLs.</p> <p>My issue is that I have multiple objects stored in my bucket with an ACL permission of access to owner only. I need to be able to create URLs that allow timed access. However, <a href="http://docs.amazonwebservices.com/AmazonS3/latest/S3_QSAuth.html" rel="nofollow noreferrer">the documentation for Amazon S3</a> is very brief on the subject.</p> <p>Could someone elaborate, or provide a link to something that explains how I might achieve this in PHP?</p>
