Statically analyzing PHP code

Tool support in IDEs for PHP code is limited due to the dynamic nature of the language. Mark Hills, Jurgen Vinju and Paul Klint produced a principled yet pragmatic infrastructure for analyzing PHP code nevertheless. The analyses first use crude but effective over-approximations of the PHP semantics to limit the search spaces and improve accuracy, then exploit information from user-manuals, and then use state-of-the-art static analysis techniques in a fixed point abstract interpretation to arrive at accurate results.
