does file_get_contents() break law?
I would like to know if there is a page(e.g. Facebook, Google, SO, ...) and I "redirect"* it to my page using file_get_contents, it brakes the law?

I mean by redirect this:

- putting file content to my site
- according to the source including js,css,etc
- replacing links not to navigate back to the original site

Possible aim of this:

 - modify pages  
 - getting information about user
