Example of how to convert public and lunar dates 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:
<?php
/*
*
* 陈海波 新二级页面 农历转换成公历
*
* */
// lunar.php 新建这个php文件，所有的代码无需改，需要改的是下面teacher.php 的几行
class Lunar
{
private $_SMDay = array(1 => 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

Explain JSON Web Tokens (JWT) and their use case in PHP APIs.
Apr 05, 2025 am 12:04 AM
JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1.

When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,
