PHP Support in Expression Web 2
For those who might wonder about how open Microsoft is to third-party development tools and/or languages, here's one answer:
In response to feedback from Expression Web 1 users, we’ve added a rich set of features for PHP development in Expression Web version 2. There are the expected productivity features such as code-coloring, snippets and IntelliSense™, but it doesn’t stop there. The product now ships with a PHP development server that lets you test your PHP pages without any other external web server dependencies (e.g. IIS or Apache). Essentially, PHP is now a first-class citizen in Expression Web 2, and will continue to be in upcoming versions of the product.
