Convert absolute to relative url with preg_replace

(I searched and found many conversion questions regarding absolute URLs, but nothing for absolute relative.)

I would like to enter data from the form field and eventually get the relative url. Ideally, this could work with any of the following inputs and end /page-slug.

  • http://example.com/page-slug
  • http://www.example.com/page-slug
  • https://example.com/page-slug
  • https://www.example.com/page-slug
  • example.com/page-slug
  • /page-slug
  • And maybe I don’t think about ... anymore?

Edit: I would also like this to work for something where the relative URL, for example. /page/post(i.e. something with more than one slash).
