PHP Development method for converting the Gregorian calendar into lunar calendar and showing solar terms and holidays (PHP Class)

This article mainly introduces the development of PHP into the lunar calendar and display solar terms, holidays and methods (PHP Class), has a certain reference value, now share to everyone, the need for friends can refer to
