<?php
class check_IdCard {

  if (strlen($num) != 15 && strlen($num) != 18) {
   return false;
  }
  // 是数值
  if (is_numeric($num)) {
   // 如果是15位身份证号
   if (strlen($num) == 15) {
    // 省市县(6位)

//3-4位地级市、盟、自治州代码;
//5-6位县、县级市、区代码;
//7-14位出生年月日,比如19670401代表1967年4月1日;
//15-17位为顺序号,其中17位男为单数,女为双数;
//18位为校验码,0-9和X,由公式随机产生。
//举例:
//130503 19670401 0012这个身份证号的含义: 13为河北,05为邢台,03为桥西区,出生日期为1967年4月1日,顺序号为001,2为验证码
//===========15位身份证号码各位的含义:=======================
//1-2位省、自治区、直辖市代码;
//3-4位地级市、盟、自治州代码;
//5-6位县、县级市、区代码;
//7-12位出生年月日,比如670401代表1967年4月1日,这是和18位号码的第一个区别;
//13-15位为顺序号,其中15位男为单数,女为双数;
//与18位身份证号的第二个区别:没有最后一位的验证码。
//举例:
//130503 670401 001的含义; 13为河北,05为邢台,03为桥西区,出生日期为1967年4月1日,顺序号为001。

Explain JSON Web Tokens (JWT) and their use case in PHP APIs. 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. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. 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,
