Code

function _spamspan_callback_mailto($matches) {

  // take the mailto: URL in $matches[2] and split the query string
  // into its component parts, putting them in $headers as
  // [0]=>"header=contents" etc.  We cannot use parse_str because
  // the query string might contain dots.
  $headers = preg_split('/[&;]/', parse_url($matches[2], PHP_URL_QUERY));

  // if no matches, $headers[0] will be set to '' so $headers must be reset
  if ($headers[0] == '') {
    $headers = array();
  }
  return _spamspan_output($matches[3], $matches[4], $matches[5], $headers);
