The Interoperability Team at Microsoft is announcing the availability of an update to the Windows Azure Tools for Eclipse and is shipping a new Community Technology Preview (October 2010 CTP) of the Windows Azure Tools for Eclipse for PHP. This Eclipse plug-in provides PHP developers using Eclipse with tools to create and deploy web applications targeting Windows Azure.
Brian Swan has developed a complete tutorial “Using the Windows Azure Tools For Eclipse with PHP” and can be found here: http://blogs.msdn.com/b/brian_swan/archive/2010/10/12/using-the-windows-azure-tools-for-eclipse-with-php.aspx
If you are interested in interoperability on the Windows Azure Platform including PHP and other solution accelerators I recommend reading the summer campaign articles I ran last summer. You can find the related materials here: http://msdn.microsoft.com/nl-be/ff877809.aspx
