Mapping a (lagcy) PHP application

Hello everyone,

I inherited a legacy application/code which was originally written in PHP4,
and letter on was "upgraded" to PHP5.

the code is (mostly) a collection of individual pages which are stitched
some how together to form a working web-application.

the code base is quite big and I'm looking for a tool which can create some
sort of a (visual) work-flow view of the code, just so I could get a
overview of the application.

I googled a bit and found a tool called phpCallGraph which won't run and it
seems is not minted any more.

Some one on stackoverflow
<http://stackoverflow.com/questions/2719734/php-application-flow-graph-or-function-call-graph>
suggested to use xdebug profiling option and visualize the result with
KCacheGrind, but it didn't give me what is hopping for - a workflow.

Do anyone have any suggestion for a tool which can help me to get a
work-flow for the application ?

Thanks in advance
