James Senior just posted about a new PHP tutorial for the Messenger Web Toolkit:

A common misconception is that the cool functionality in the Windows Live Messenger Web Toolkit is only available to developers who are using the Microsoft web platform i.e. ASP.NET.  This couldn’t be further from the truth. 

The Windows Live Messenger Web Toolkit is entirely client-side based using JavaScript and HTTP endpoints, it will happily run on any platform, any web server and with any scripting language.  The Web Toolkit JavaScript was created using Script# which allows you to code in C# and then compile down to JS – neat.

For PHP developers we’ve just released a couple of cool things to allow you to put Windows Live Messenger in your web apps:

This means if you code your web apps in PHP, Ruby, Perl etc. you can go ahead and use the Windows Live Messenger Web Toolkit to light up your apps and create cool new social scenarios for people that visit your website.

Enjoy, and let me know how you get on!
