I don't know too much about anything you listed either, but... Scalpel
is a C++ parser, GCCSense seems to be tools that use gcc's C++ parser,
and clang is a C/C++/Objective-C parser. LLVM is language-agnostic but
afaik the information it has is in a different level (made for
compiler optimization, not for source code knowledge).

DUchain is not a parser, it's a language-agnostic framework storing
information about code. There is nothing C++-specific in it. KDevelop
has a C++ parser that loads stuff into duchain data structures, but
there is also a high-quality plugin doing the same for PHP, and some
others in development for other languages.

I don't really see the other projects you listed going to implement
support for PHP or Python or CMake anytime soon ;)

However, those projects are still interesting, and there may be
possibilities of integrating them into KDevelop. For example, someone
was experimenting with replacing KDevelop's C/C++ preprocessor with
Boost.Wave, which is way more standards-compliant. And maybe clang's
API is suitable for integrating it in DUChain...
