PHP와 Vue를 결합하여 직원 출석에 대한 체크인 및 체크아웃 기능을 구현하는 방법

<?php
include 'db_connect.php';

// 接收从前台传来的员工ID
$employee_id = $_POST['employee_id'];

// 获取当前时间
$sign_in_time = date('Y-m-d H:i:s');

// 将签到信息插入到数据库
$sql = "INSERT INTO attendance (employee_id, sign_in_time) VALUES ('$employee_id', '$sign_in_time')";
$result = mysqli_query($conn, $sql);

if ($result) {
  echo "签到成功";

// 接收从前台传来的员工ID
$employee_id = $_POST['employee_id'];

// 获取当前时间

// 更新签退时间
