How to get list of EC2 instances with Amazon PHP SDK 2?

Question

How to get list of Amazon EC2 instances matching some filters using AWS SDK for PHP 2?

Answer 1

Victor's answer is great, but it wasn't working for me because I was missing one line:

$reservations=$result->toArray();

The Amazon PHP SDK 2 returns Guzzle Model objects for many things (including this), and they need to be converted to arrays before foreach will work. More info here:
