hash_hamc is not always available. You could check with:

if (extension_loaded ('hash')) {
  hash_hmac ('sha1', $str, $key, true);
} else {
  //use hand_crafted_version

I believe it is if you are on PHP 5.3 or later. Before that, this
should do it:

function oauth_encode ($str) {
  return str_replace ('%E7', '~', rawurlencode ($str));
