太陽暦から旧暦に変換する際のデジタル年が正しくない

グレゴリオ暦から太陰暦に変換するときのデジタル年が正しくありません
以下のコード内
$lunarCalendar = getLunarCalendar(2015,1,12);
echo $lunarCalendar['year' ];//ここ 旧暦は 2014 年であるはずですが、出力では実際に 2015 年であることが示されています
次のコードで正しい旧暦を取得するにはどうすればよいですか? ?

function getLunarCalendar($year, $month, $day)
{
// 太陰暦の各月の日数

----- -解决思路----------------------
你先握纪元弄明再说

$lunarCalendar = getLunarCalendar(2015,1,12);<br />print_r($lunarCalendar);<br />

Array<br />(<br />    [year] => 2015<br />    [yearname] => 甲午(马)年<br />    [displaymonth] => 十一月<br />    [displayday] => 廿二<br />    [displayweek] => 星期一<br />    [month] => 11<br />    [day] => 22<br />)<br />

返還的两套纪元、是混着用不可
-----解决思路----------------------
农历里是2014 年はなく、計算方法が異なるため、このように計算することはできません。たとえば、一部の月は午月です。
