PHP achieves mutual conversion between Gregorian and lunar dates

Preface:

Today, according to the customer's needs, the time was converted, that is, the customer requested to increase the display of the lunar date, copied a section on the Internet, and slightly modified it to run successfully, it is not difficult, few changes.

Sample Code:
