I got this from a friend in the CS462 class that hasn't posted it yet.

For those of you that need a nice tool for connecting to AWS with php...
Tarzan is a fast, powerful PHP toolkit for building web applications with Amazon Web Services.

My experience:
Setup was semi painless.
Their docs page wasn't too complicated.
I haven't actually implemented anything with it yet but it looks pretty simple compared to phpcurl.
