PHP framework to build Workflow Management system

Question

Hello, I am looking for PHP framework to build a Workflow Management system. While searching on net i got RADICORE which is quite best one. Just looking for more option so that I can compare them and go with one of them

My requirement is as: I need framework that can define a workflow as we do in RADICORE and then play around it. Playing means that if there 4 steps in my workflow, i can drop one and see How the workflow proceeds. There are many frameworks through which you can generate a graph of your existing flow. So i am basically interested in defining a workflow rather than generating the graph for existing framework.

And i should be an open source framework (basically PHP).

Answer 1

Zeta/ezComponents has a Workflow engine.. It's OpenSource and free to use. No clue how that compares to other engines though.
