如何结合PHP和Vue实现员工考勤的迟到早退提醒

<?php
// 连接数据库
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "attendance";

$conn = new mysqli($servername, $username, $password, $dbname);
if ($conn->connect_error) {
    die("连接数据库失败：" . $conn->connect_error);
}

// 查询员工的考勤记录
$sql = "SELECT * FROM attendances WHERE employee_id = '1'";
$result = $conn->query($sql);

if ($result->num_rows > 0) {
    // 输出数据
    while($row = $result->fetch_assoc()) {
        // 判断是否迟到或早退
        if ($row["is_late"] || $row["is_early"]) {
            // 发送提醒
            $message = "您有迟到或早退的记录，请注意改进";
            // 使用邮件或短信等方式发送提醒
            // ...
        }
    }
} else {
    echo "没有找到相关的考勤记录";
}

$conn->close();
?>

<template>
  <div>
    <h1>我的考勤记录</h1>
    <table>
      <tr v-for="attendance in attendances">
        <td>{{ attendance.date }}</td>
        <td>{{ attendance.actual_start_time }}</td>
        <td>{{ attendance.actual_end_time }}</td>
        <td v-if="attendance.is_late">迟到</td>
        <td v-if="attendance.is_early">早退</td>
      </tr>
    </table>
  </div>
</template>

<script>
export default {
  data() {
    return {
      attendances: []
    }
  },
  mounted() {
    // 使用Ajax或Axios等方式从后端获取考勤记录
    // 并赋值给attendances数组
  }
