Uploading files remotely on Selenium WebDriver via PHP

[evons]

I've been searching around StackOverflow (and other resources) on how to remotely upload files on Selenium WebDriver via PHP. I've read this http://saucelabs.com/blog/index.php/2012/03/selenium-tips-uploading-files-in-remote-webdriver/, and it mentions that you need to use a "setFileDetector" method somehow to change the way the webdriver library you're using works.This should work fine if I was using Ruby or Java. Most PHP frameworks on the other hand don't have this method.Can anybody tell me how to do this in PHP? Specifically, I'm using the phpwebdriver library http://code.google.com/p/php-webdriver-bindings/
