title: What PHP IDE's have outside of file Syntax Highlighter's?
body: <p>I am not looking for a debate on best, I just want to know what PHP IDE's have features for highlighting classes, functions and any other relationships <strong>outside of the viewed page</strong>, to save time on scrolling through pages of code. I would be accessing MVC like frameworks and want this to extend off of my existing page, so covering the actual project.</p>
  
  <p>I have a handful of IDE's I am playing with, but yet to find something that extends to full project as well as I would like. Or maybe I have not used these to their full potential. Any thoughts or ideas would be greatly appreciated. I also have looked for IDE's recently to help with CMS projects, but that is a whole other story and would likely create a debate.</p>
