How to save content/text of a web page by forcing save-as option

[randy.]

I would like to know what would be the best way to save contents from a web page. I mean to force save-as option by clicking a link or button. I often found that javascript would not be an option because it's only working for IE, so I thought that it would be easier because javascript is client-side based.Now, I thought maybe there is a way to use php when creating a form that will redirect it over a server site query to return and force the save-as option. My main goal is make it possible to save the privacy terms. I would like to avoid using fpdf. If there is someone who could tell how to solve this I would really appreciate it.
