Introduction to the method of converting between the Gregorian calendar and the lunar calendar in PHP

This article mainly introduces the relevant information on PHP to realize the conversion between Gregorian calendar dates and lunar calendar dates. I hope that this article can help everyone. Friends in need can refer to the following

PHP realizes the Gregorian calendar Conversion between dates and lunar calendar dates

Foreword:

Today, the time was converted according to the customer's needs, that is, the customer requested to increase the display of the lunar calendar date. I plagiarized a paragraph from the Internet, modified it a little and it ran successfully. It is not difficult and has very few changes.

Sample code:

 31, 28, 31, 30, 31, 30, 31, 31, 30, 31, 30, 31);//定义公历月分天数 
 private $_LStart = 1950 ;//农历从1950年开始 
 private $_LMDay = array( 
  //差：该年的农历正月初一到该年公历1月1日的天数；1~12：农历月份天数；闰：如有闰月，记录该月平月天数 
  //  差 1 2 3 4 5 6 7 8 9 10 11 12 闰 
  array(47,29,30,30,29,30,30,29,29,30,29,30,29), 
  array(36,30,29,30,30,29,30,29,30,29,30,29,30),
