In a recently posted tutorial on the Zend Developer Zone website, Cal Evans has pointed out a video showing PHP pushing videos out to YouTube.

Attention all you Zend Framework junkies, Jochen Hartmann has uploaded a new video to YouTube that demonstrates the basics of how to use Zend Framework with the YouTube Data API. This step-by-step demonstration walks you though everything you need to know to upload files to Youtube via Zend Framework.

The video (from the official Google developers) shows the creation of a simple application that uses the Google Data component of the Zend Framework to upload the selected video from their local machine.

You can find out more about the Google API for YouTube on this page on the Google Code website.

In this new tutorial on the IBM developerWorks website, they show you how - with a little simple HTML and PHP - to integrate functionality from the YouTube API into your site.

The YouTube video sharing site allows Web application developers to access public content through its REST-based developer API. [...] This article introduces the YouTube Data API, demonstrates how you can use it to browse user-generated video content; access video metadata, comments and responses; and perform keyword searches.

They help you get started by outlining the format that the YouTube messages use (Atom feeds) and how to run a query against the API and return back the custom data for things like video categories, popularity and the results of keyword searches.
