    $iCharLength = strlen($sBase);
    $sRandom = '';

    for ($iCnt = 0; $iCnt < $iLength; $iCnt++)
    {
        $sRandom.= $sBase[rand(0, $iCharLength - 1)];
    }

    $sString = uniqid(microtime(true), true)
        . '.' . $sRandom;
    $sString = preg_replace('/[^a-zA-Z0-9]+/', '-', trim($sString));
