Object Storage Service:OSS SDK for PHP 2.0

<?php

/**
 * Complete guide to OSS SDK for PHP 2.0 client configuration
 *
 * ===========================================
 * V4 signature and region configuration
 * ===========================================
 * • OSS SDK for PHP 2.0 uses the V4 signature algorithm by default.
 * • You must specify an Alibaba Cloud region ID when initializing the client.
 * • For a list of region IDs, see Regions and endpoints.
 *
 * ===========================================
 * Endpoint configuration
 * ===========================================
 * • The SDK lets you customize the service endpoint by using the endpoint parameter.
 * • If you omit the endpoint, the SDK automatically constructs a public endpoint from the region information.
 * • For example, if the region is '<region-id>', the constructed endpoint is 'https://oss-<region-id>.aliyuncs.com'.
 *
 * ===========================================
 * Protocol selection
 * ===========================================
 * • The SDK uses HTTPS by default to construct endpoints, which is the recommended protocol.
 * • To use the HTTP protocol, include http:// in the endpoint.
 * • HTTPS example: 'https://oss-<region-id>.aliyuncs.com'
 * • HTTP example: 'http://oss-<region-id>.aliyuncs.com'
