PHP date operation code-Lunar calendar-Gregorian calendar conversion, leap year, calculation of days, etc.

This is a practical PHP date and time operation class, which includes Gregorian calendar-lunar calendar conversion, conversion to Chinese date format, calculation of the number of days between lunar calendars, obtaining the zodiac sign according to the lunar calendar year, obtaining the number of days in the lunar calendar month, and obtaining the lunar calendar The number of days in each year, obtaining leap months, calculating the number of days between the lunar date and the first day of the first lunar month, calculating the number of days between two Gregorian calendar (solar calendar) dates, calculating the lunar calendar date based on the number of days from the first day of the first lunar month, obtaining the chronology of the heavenly stems and earthly branches, etc., PHP date Operation class: Lunar.class.php code is as follows:
