Anyone Using PHP with NUSOAP for adCenter API? Have an example for the KeywordPerformanceReport?

In the adCenter API forums, in the thread "adCenter Reporting Service", a developer this week asked for assistance using PHP with NUSOAP. He is trying to specifically get the KeywordPerformanceReport in PHP.

Though we haven't received this question before, we know that NUSOAP is fairly common. The value of developer community is realized when users are able to share examples from similar cases. Granted, it's possible that nobody else has done this.

So how about it? Has anyone coded to the API using PHP with NUSOAP? Do you have an example for how to get the KeywordPerformanceReport? Willing to share advice or examples?
