title: How to convert torrent info hash for scrape?
body: <p>I have a torrent hash from the magnet link. For example: fda164e7af470f83ea699a529845a9353cc26576
  When I try to get information about leechers and peers I should request: <a href="http://tracker.publicbt.com/scrape?info_hash=" rel="nofollow noreferrer">http://tracker.publicbt.com/scrape?info_hash=</a>???
  How should I convert info hash for this request? Is it url encoding or becoding? how? In PHP.</p>
