Phalanger project was developed as student project at Mathematics and Physics Faculty, Charles University in Prague. It is a PHP language to Microsoft Intermediate Language compiler cooperating with ASP.NET to provide full support of PHP web applications. A part of the project is also integration of PHP language into MS Visual Studio environment.
My work at this project was integration of PHP language into MSVS and internal compiler structures (compiler tables). I do not work at this project already, Tomáš Matoušek and Ladislav Prošek continue in the development. They switch to .NET FW v2.0 and extend PHP language compiled by Phalanger with generics and other cool stuff :)
All inforation about the project could be found at project's web page.
