I'm looking for the best approach to dealing with duplicate code in a legacy PHP project with about 150k lines of code.
Is this something best approached manually or are there standalone duplicate code detectors that will ease the pain?

I wish to get a quick feeling for how much “copy and paste” coding we have, there are many tools for C# / Java to check for this type of thing. Are there any such tools that work well with VB.NET?

I did the same thing using a master page, using ASP:Hyperlink controls .
You could expose a Bool on each page.
Create a UserControl for your common code and add a reference to each page.

This way you can call something like a CreateRow method ... .
One way to do this is to expose the logic that generates the markup as a web service on your server and have JavaScript get that markup via an AJAX call rather than duplicating the logic.

While it doesn't replace redundant code with function calls, it does.
See the C# CloneDR.
A section soon.
That is, it scans your code, searching for sections that can be replaced by an existing method call.
