What happened to the PHP Expense Tracker application?

Hi, 

I was looking at using PHP from an external website to access a Creator Form and cam across this blogpost which looked interesting... 

http://blogs.zoho.com/creator/apis-for-zoho-creator

But the link to the example provided (or at least I got the impression that this example was PHP source code)... http://creatorapps.zoho.com/ is broken...

Is there an alternative I can look at, or can anyone else provide some PHP code examples for accessing Zoho Forms from external websites?

Regards, 

Liam
