XHP has transformed how PHP is written at Facebook. An open source augmentation of the PHP language to allow XML document fragments as valid expressions, XHP changes the way front end code is developed. Using these XHP objects instead of string literals to output HTML has eliminated XSS vulnerabilities, prevented missing closing tags, and stopped invalid markup.
Learn some of the tricks Facebook has developed over the past 18 months building the first UI framework on top of XHP and see how it can be leveraged for any sized web application. I'll discuss how XHP can be used to build adaptable grid layouts, templating architectures, and progressively enhanced HTML, as well as demo how it can radically reduce the amount of time to rebuild a new site design.
