Replacement for PHP's get_browser() function

Code

function browscap_get_browser($useragent = NULL) {
  if (!$useragent) {
    $useragent = $_SERVER['HTTP_USER_AGENT'];
  }

  // Cache the results
  $cacheid = $useragent;

    $browserinfo = unserialize($cache->data);
  }
  else {

    // the wildcarded pattern to match against our full-length string
    // The ORDER BY chooses the most-specific matching pattern
    $browserinfo = db_fetch_object(db_query_range("SELECT * from {browscap} WHERE '%s' LIKE useragent ORDER BY LENGTH(useragent) DESC", $useragent, 0, 1));

    // A couple of fieldnames not in our database, provided for
    // compatibility with PHP's get_browser()
