If you are using PHP to talk to the YouTube Data API, you may want to
check out the new Developer's Guide that we just released. This guide
features several improvements to the existing v1 PHP client library
methods and also adds support for version 2 only functionality such as
new query parameters:

In addition, we have also created a 'migration guide' that highlights
the specific differences to be aware of when migrating from version 1
to version 2:

Please note that you will need to use at least version 1.7.2 of the
PHP client library (the current version is 1.7.4).
To get started, download it from the Zend Framework site:
