function getCreditCardExpiryYears($yearsFromNow = 10)
{
    if ( ! is_numeric($yearsFromNow)) $yearsFromNow = 10;

    $thisYear  = date('Y');
    $untilYear = $thisYear + $yearsFromNow; // e.g. 2012 + 10 = 2022 

    $years = array();
    for ($i = $thisYear; $i <= $untilYear; $i++)
    {
        array_push($years, $i);
    }
