Hi Emily,

This is just a suggestion when working with PHP and the AdWords API: Google has developed an OpenSource PHP library for interacting with the AdWords API which can be found here:

-> http://google-apility.sourceforge.net/

APIlity has implemented UTF-8 support using an adapted version of nusoap. You might want to give it a try...

There is an own developer forum for PHP- and APIlity-related questions which can be found here:

-> http://groups.google.com/group/adwords-api-php

The Criterion.php alpha version is about to be implemented and can be found here: -> http://groups.google.com/group/adwords-api-php/browse_thread/thread/8297efb23390f845

Let me know if this solves your problems if you feel like.

Hope this helps.

Best wishes, Tom
