This article mainly introduces PHP's implementation of the conversion from the Gregorian calendar to the lunar calendar. The example analyzes the principle and implementation skills of the conversion from the Gregorian calendar to the lunar calendar, which has some reference value, for more information, see the examples in this article. Share it with you for your reference. The details are as follows:

The code is as follows:
