Doubt over WEBVIEW on Phonegap

Good morning, I'm not sure if this is called a Webview, so please correct me if I'm wrong, please. I have a website, and I'm introducing my studies now in application development, and for the knowledge I have in programming and web development, Phonegap seemed perfect. Which brings me to some doubts for the development of this project that I am in mind. I understand that php does not run on the phonegap after a few minutes searching, but I'd like to know what the way to render a site within the application is, I know I can use an iframe, but still I do think I have more " and useful than this. Please, if you can clarify, I would be very grateful. I thank the attention! Great day guys!
