<?php // @codingStandardsIgnoreStart // This is a compatibility library, using Amazon's official PHP SDK (PHP 5.3.3+), but providing the methods of Donovan Schönknecht's S3.php library (which we used to always use) - but we've only cared about making code-paths in UpdraftPlus work, so be careful if re-deploying this in another project. And, we have a few bits of UpdraftPlus-specific code below, for logging. /** * * Copyright (c) 2012-22, David Anderson (https://www.simbahosting.co.uk).
