PHP framework to build Workflow Management system

Question

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.

Answer 2

I can suggest formapro/pvm library.

The library provides us with a frame to build a workflow or business processes such as BPMN. It works like this: you build a process, create nodes and transitions, link them up. Then you can do:

• Save process and execute later.
• Clone and execute several processes.
• Pause & continue execution.
• Supports async transition. Execute tasks in parallel.
• Supports fork-join, conditions, cycles and so on.

It is backed up by workflow nets (WF-nets) and graphs theories. . Here's a good post on how Petri Nets works

It's very powerful and at the same easy to use (thanks to Petri Nets theory).
