For PHP it can be done like so:

$str = 'magnet:?xt=urn:btih:74651f66e937698dc5ac1e0e252f44795070a7b5&dn=archlinux-2017.03.01-dual.iso&tr=udp://tracker.archlinux.org:6969&tr=http://tracker.archlinux.org:6969/announce';

if(preg_match('/magnet:\?xt=urn:[a-z0-9]+:[a-z0-9]{32,40}/', $str)){
  echo 'valid';
}

But this only checks if the format is in order, you don't know if the magnet link will work unless you try it out.
