Lunar calendar algorithm example implemented by php

This article mainly introduces the lunar calendar algorithm implemented by php, and analyzes in detail the principles of the lunar calendar algorithm and php implementation skills, which is of great practical value, for more information about the lunar calendar algorithm implemented by php, see the examples in this article. Share it with you for your reference. The details are as follows:
