Phalanger, the PHP runtime for .NET and Mono, has reached a significant milestone with the eleven popular PHP extensions being replaced with .NET equivalents. Previously these extensions, written in native C or C++, were limiting Phalanger to only running in 32-bit mode.
Phalanger 3 is out with improved support for PHP namespaces, Mono/Linux, and C# interoperability.
Phalanger is a PHP compiler for the .NET and Mono runtime. It is currently capable of running popular PHP based applications such as WordPress. With the exception of indirect invocation of static methods, Phalanger now offers across the board performance improvements over PHP.
