With a few handy scripts and a Windows box Harry Fuecks takes the Activescript SAPI and creates client-side PHP scripts for Internet Explorer.

While messing with PHP 5.0.0 figured it's finally time to take at Wez Furlongs Activescript SAPI for PHP. Will the madness never end? ;)

In brief Microsoft provide a mechanism in Windows to "embed" scripting engines (e.g. PHP) and thereby allow execution of code in other languages. More information can be found at MSDN on Windows Script Interfaces.

The concept is simple and, thankfully, so is the installation (well, at least the PHP part of things). Just make the directory, point the your browser at it, and you're good to go.

Now all we need is Microsoft to bundle it with IE ;) Back to reality, where is actually might be useful is if you want to write Windows sysadmin scripts in PHP.
