Lucky me (and my client), when changing the layout, the nice guys at FilesTube built an API also, as thoroughly technically described here. There’s an example too, and although it looks like a bunch of unmaintained code, it works out of the box. Actually, it does if your server meets these requirements (which I couldn’t find anywhere on FilesTube’s website):

• It runs PHP 5, which is now the standard PHP version. I believe however, that you can use PHP 4 to achieve the exact result.
• It has cURL enabled. This is, again, not a problem, since almost every hosting provider has it by default. Yours doesn’t? Well, it’s time to move dude. Being a conservative? You may try file_get_contents() instead.

The way it works is, just send a search phrase along with a uinique (and free!) API key to http://api.filestube.com/ (there are some other options available: related, sort, page, and extension), and receive back an XML string. Something like this:

As you can see, everything’s there. Now use a DOMDocument object to parse the XML string. Piece of cake.

The (running well) result can be seen here. No, I’m not associated with this website in anyway.
