Simple PHP code to push files to AWS S3

So you have a web application, website or game with a PHP back-end. One of your use case is saving files to disk (images, Excel or what not). Its 2017 and you figure you should probably use a storage service instead of saving and serving files from your server.

Wait a minute, do you have to install the world to simply push a file to S3?

Here’s how I used it in my projects.

Create a php file with creds required, along with your region, and bucket name. Here’s a simple way to do that. Notice I conditionally load the constants only in prod. This allows me to fallback to local file storage instead (described in step 3) — very useful for development.

Saving to AWS is very simple. Donavan provided simple static methods to allow this. In the case AWS is not available (i.e. dev environment) I fallback to saving to a file.

There you have it. Easy peasy PHP push to S3.
