With the development of the Internet, more and more companies have begun to implement electronic attendance records, which not only improves work efficiency, but also reduces the occurrence of human errors. However, in electronic attendance records, how to implement the audit function of employee attendance records is still a problem that needs to be solved.

PHP is a commonly used server-side scripting language, suitable for developing dynamic web pages and web applications. In PHP, we can use some techniques and methods to implement the audit function of employee attendance records. Below, I will introduce the specific implementation steps and sample code in detail.

Database design
First, we need to design a database to store employee attendance records. We can create a table with the following fields: employee name, attendance date, attendance status, etc. For example:

CREATE TABLE attendance (
  id INT AUTO_INCREMENT PRIMARY KEY,
  employee_name VARCHAR(50) NOT NULL,
  attendance_date DATE NOT NULL,
  attendance_status ENUM('出勤', '缺勤', '迟到', '早退') NOT NULL,
  is_approved BOOLEAN DEFAULT FALSE
);

Front-end interface
Next, we need to create a front-end interface for auditors to view and review employees' attendance records. The interface can include a table that displays employee attendance information and provides a button for reviewers to review. For example:

<!DOCTYPE html>
<html>
<head>
    <title>员工考勤审核</title>
    <style>
        table {
            border-collapse: collapse;
            width: 100%;
        }

        th, td {
            padding: 8px;
            text-align: left;
            border-bottom: 1px solid #ddd;
        }

        tr:hover {
            background-color: #f5f5f5;
        }

        .approve-btn {
            background-color: #4CAF50;
            border: none;
            color: white;
            padding: 10px 15px;
            text-align: center;
            text-decoration: none;
            display: inline-block;
            font-size: 16px;
            margin: 4px 2px;
            cursor: pointer;
        }
    </style>
</head>
<body>
    <h2>员工考勤审核</h2>
    <table>
        <tr>
            <th>员工姓名</th>
            <th>考勤日期</th>
            <th>出勤状态</th>
            <th>审核状态</th>
            <th>操作</th>
        </tr>
        <?php
        // 获取考勤记录列表
        $records = getAttendanceRecords();

        // 循环输出考勤记录
        foreach ($records as $record) {
            echo '<tr>';
            echo '<td>'.$record['employee_name'].'</td>';
            echo '<td>'.$record['attendance_date'].'</td>';
            echo '<td>'.$record['attendance_status'].'</td>';
            echo '<td>'.($record['is_approved'] ? '已审核' : '未审核').'</td>';
            echo '<td><a href="approve.php?id='.$record['id'].'" class="approve-btn">审核</a></td>';
            echo '</tr>';
        }
        ?>
    </table>
</body>
</html>

Backend logic
In the backend, we need to write some PHP code to implement the audit function of employee attendance records. First, we need to write a function to get the attendance record list, for example:

function getAttendanceRecords()
{
    // 连接数据库
    $conn = mysqli_connect('localhost', 'username', 'password', 'database');

    // 查询考勤记录
    $result = mysqli_query($conn, 'SELECT * FROM attendance');

    // 将结果转换为数组
    $records = mysqli_fetch_all($result, MYSQLI_ASSOC);

    // 关闭数据库连接
    mysqli_close($conn);

    return $records;
}

Then, we need to write a script approve.php that handles the audit. This script receives the ID of an attendance record as a parameter and updates the corresponding review status to Reviewed. For example:

// 获取考勤记录ID
$recordId = $_GET['id'];

// 连接数据库
$conn = mysqli_connect('localhost', 'username', 'password', 'database');

// 将考勤记录的审核状态更新为已审核
mysqli_query($conn, 'UPDATE attendance SET is_approved = 1 WHERE id = '.$recordId);

// 关闭数据库连接
mysqli_close($conn);

// 跳转回审核页面
header('Location: index.php');

Through the above steps, we can use PHP to implement the audit function of employee attendance records. When the auditor clicks the audit button, the approve.php script will be triggered to update the audit status of the corresponding attendance record to audited.

The above are the specific steps and sample code on how to implement the audit function of employee attendance records through PHP. Hope this helps everyone!
