This article mainly introduces the classes and usage of PHP to obtain the lunar calendar (lunar calendar), festivals, and solar terms. It analyzes the specific definition of the PHP date tool class Lunar and the related operation skills for obtaining lunar dates, solar terms, etc. in the form of examples.
