Remove “www”, “http://” from string

Question

How can I remove \"www\", \"http://\", \"https://\" from strings using Ruby?

I tried this but it didn\'t work:

s.gsub(\'/(?:http?:\\/\\/)?(?:www\\.)?

This method should catch all 3 variations:

def strip_url(url)
  url.sub!(/https\:\/\/www./, '') if url.include? "https://www."

  url.sub!(/http\:\/\/www./, '')  if url.include? "http://www."

  url.sub!(/www./, '')            if url.include? "www."

  return url
end

strip_url("http://www.google.com")
   => "google.com" 
strip_url("https://www.facebook.com")
   => "facebook.com" 
strip_url("www.stackoverflow.com")
  => "stackoverflow.com"
