Amazon S3 integration with Symfony2 and Gaufrette

Its amazing how Symfony2 has created an ecosystem where you can just add a bundle to your application and in minutes, you are able to make use of functionality/integration that would take you days to add if you had to code it up yourself. A while ago, I needed to add S3 CDN support to our Loosemonkies application so that the avatars uploaded by job seekers and company logos uploaded by employers would be stored in a globally accessible CDN. I started looking for a ready-to-use bundle that I can just add to the project, beef up a few config and everything else would just work. However, this time the task seemed a bit tough.

After much searching and evaluating, I stumbled upon this wonderful post. The author has shown here how to use Gaufrette and the Amazon AWS bundle together to achieve what I was looking for. It took me a while to follow the steps and finally I integrated it. Then I had a new requirement where I would need to upload assets that have already been sitting in the local, so I would add an additional method in the PhotoUploader class to handle it – uploadFromUrl. It would guess the mime type of the file by extension, as we do not have the mime type handed to us by PHP. It worked beautifully and we were all set.

Sharing the code here in case others find it useful.
