如何使用PHP类实现阳历转农历转换功能？

phpclass Calendar { // 将农历转换为公历 public function lunarToSolar($lunarYear, $lunarMonth, $lunarDay) { // 这里使用了一个简化的算法，实际应用中可能需要更复杂的计算 $solarDate=\DateTime::createFromFormat('Y-m-d', $this->lunarToGregorian($lunarYear, $lunarMonth, $lunarDay)); return $solarDate->format('Y-m-d'); }

// 农历转公历 private function lunarToGregorian($lunarYear, $lunarMonth, $lunarDay) { // 这里同样使用了一个简化的算法 $baseYear=1900; $offset=$this->lunarYearOffset($lunarYear); $day=$offset + $lunarDay; $month=1; while ($day > 0) { $daysInMonth=$this->daysInLunarMonth($lunarYear, $month); if ($day > $daysInMonth) { $day -=$daysInMonth; $month++; } else { break; } } return sprintf('%d-%d-%d', $lunarYear, $month, $day); }

// 获取农历某年某月的天数 private function daysInLunarMonth($year, $month) { // 这里同样使用了一个简化的算法 $days=[31, 28, 31, 30, 31, 30, 31, 31, 30, 31, 30, 29]; // 平年 if ($this->isLeapYear($year)) { $days[1]=29; // 闰年 } return $days[$month - 1]; }

// 判断是否为闰年 private function isLeapYear($year) { // 这里同样使用了一个简化的算法 return ($year % 4==0 && $year % 100 !=0) || ($year % 400==0); }

// 获取农历某年的偏移量 private function lunarYearOffset($year) { // 这里同样使用了一个简化的算法 $offset=0; for ($i=1900; $i isLeapYear($i) ? 366 : 365; } return $offset; }}
