1,設計想法:
要想計算給定的時間對於的農曆是哪一天，我們需要找一個參考時間，然後以該參考時間計算以後的時間。先計算目前時間與參考時間相差的天數，再求出農曆每年的天數，計算目前時間對應的是哪一年的第幾天，最後計算出屬於那個月的哪一個日期。

修改calendar.php程式碼:
#新加get請求:
##echo "< ;th onmouseOver='overTh(this)' onmouseOut='outTh(this)'><a href='?convert=$ymd'>{$d}</a></th>";
呼叫封裝類別:
<?php
$convert=isset($_GET["convert"])?$_GET["convert"]:date("Y-m-d");
if($convert!=''){
$c=new Convert($convert);
$time=$c->getLyTime();
// echo $convert.'对应的农历时间：'.$time;
}
echo "<tr onmouseOver='overTr(this)'onmouseOut='outTr(this)'><td colspan='7' align='center'>";
echo "<div>$convert 对应的农历时间：$time</div>";
運行效果如下:
