Need: Free PHP to Flowchart Software/Script?
 

I am looking for a free program/script that will take PHP code and turn it into a flowchart.

I own MS Visio already so if there is one out there that will import into Visio, that would be great but not absolutely necessary.

Is there a Free Php to Flowchart Program/Script out there?
I use Windows 7 Ultimate.

Thanks for your time!
