Dynamically uploading information to S3 can be a bit challenging to do initially, particularly in PHP where a lot of the documentation is either really new or really old.Amazon has a PHP SDK , which is available as either a .phar file or can be installed using Composer . That's cool for building a new project, but what if you have a pre-existing project or form and just want to be able to dump the text output to S3?I've put together some code at Github that will take care of that issue. The only requirement is PHP and an Amazon S3 account.Download or clone the files here: https://github.com/jwieder/s3-http-php-form Your Amazon access keys and other configuration are stored in a single configuration file. Just fill out your login info into the configuration file and include the php form where you need it as outlined in the README.md file and you should be all set!
