You can install the mcrypt PHP extension with homebrew and use it with the standard PHP installation that comes with OS X.

Install mcrypt:

brew install mcrypt

Install the php extension -- this installs the whole php 5.5, but you can still use the system-provided one by default Note: install the version compatible with whatever your OS X PHP version currently is (check with php -v)

brew install homebrew/php/php55-mcrypt

AWS Lambda Event Sourcing Architecture

I'd like to have a AWS lambda / event system that allows for a certain kind of flexability, here's what I need.

• Events come in via HTTP post webhook with headers and body
  1. Store {headers, body} in one main events table where the event is named what the action is e.g. 'orderCreate', this acts as a ledger of events, with the main columns name, data, created_at.
  2. I'd like to build up the state of individual object, in their own table so for orders a table would exist with that name the event of a orderCreated the row is created and subsiquent orderDeleted the row is deleted.

3. I need a way to tap into this event and trigger some side-effect event, for instance if a orderCreated comes in to the system I also need to fire something when that comes in such as invoiceCreated I need a way to access the stream of all events and subscribe to the orderCreated and fire a invoiceCreated which ideally should repeat this process all over again
