title: PHP Application Flow Graph (or function call graph)
body: <p>Happens that I've ended up working on a big PHP program and I need a program (or easy to install script) which draws a flow control/call graph of a PHP application (ie; must work over multiple PHP files).
  Already saw stuff like Graphviz, not sure which one works for PHP?</p>
  
  <p>Any suggestions?</p>
  
  <p>Cheers!</p>
