Good cross reference tool?

Hi,

I'm looking for a tool that can generate global php variable cross references. I've seen the PHPXref application which is nice if you want to browse the source code but I am more interested in list of variables, their scope, and the line numbers in which they are used. Can anyone recommend a tool providing cross reference listings?

thanks, pd
