Can it run existing PHP applications?
Our focus has been on enabling new applications to be developed in an agile fashion using the WebSphere sMash environment rather than on enabling existing applications. That said, we recognize that being able to run existing PHP code, unchanged, is an important contributor to the productivity of a PHP programmer. As we continue to enhance our PHP language support, we are constantly testing and identifying applications that DO work on our implementation. Please see this blog post, this Developers Guide page and this Development Wiki page for more details on this work.
