(PHP Extension) Glacier Download Archive

Demonstrates how to download an Amazon Glacier archive. Downloading a Glacier archive is a two step process. First an archive retrieval job is initiated. After it completes, the job output is downloaded (i.e. the archive contents are downloaded.)

Note: This example requires Chilkat v9.5.0.78 or greater.

Chilkat PHP Downloads PHP Extension for Windows, Linux, MacOS, Alpine Linux, Solaris

<?php

// The version number (9_5_0) should match version of the Chilkat extension used, omitting the micro-version number.
// For example, if using Chilkat v9.5.0.48, then include as shown here:
include("chilkat_9_5_0.php");

// This example requires the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.

// Connect to the Amazon AWS REST server in the desired region.

// --------------------------------------------------------------------------
// Note: The above REST connection and setup of the AWS credentials
// can be done once.  After connecting, any number of REST calls can be made.
// The "auto reconnect" property passed to rest.Connect indicates that if
// the connection is lost, a REST method call will automatically reconnect
// if needed.

// To download an archive, we'll make several method calls:
// 1) Send the HTTPS GET request.
// 2) Get the response body.

// 4) If the response status code indicates an error, get the JSON error response.

// Send the GET request.
