How to use PHP to write an employee attendance exception analysis tool?

In modern enterprises, accurate statistics and analysis of employee attendance are very important for managing and optimizing enterprise resources. In order to facilitate the analysis and processing of employee attendance exceptions, we can use PHP to write a simple and powerful employee attendance exception analysis tool. The following will describe in detail how to write this tool using PHP and provide some specific code examples.

Database design

First, we need to design a database to store employee attendance information. Attendance information includes employee name, date and attendance status (normal, late, early leave, absent, etc.). We can use MySQL as the database management system and create a database named attendance, and then create a table named records to store employee attendance records.

CREATE TABLE `records` (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `name` varchar(255) NOT NULL,
  `date` date NOT NULL,
  `status` varchar(255) NOT NULL,
  PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;

Front-end page design

Next, we need to design a front-end page for entering employee attendance information and displaying exceptions. This page can be implemented using HTML, CSS and JavaScript. The following is a simple front-end page example:

<!DOCTYPE html>
<html>
<head>
    <title>员工考勤异常分析工具</title>
    <style>
        /* CSS样式 */
    </style>
</head>
<body>
    <h1>员工考勤异常分析工具</h1>
    <form action="analyze.php" method="post">
        <label>姓名：</label>
        <input type="text" name="name" required><br>
        <label>日期：</label>
        <input type="date" name="date" required><br>
        <label>考勤状态：</label>
        <select name="status" required>
            <option value="正常">正常</option>
            <option value="迟到">迟到</option>
            <option value="早退">早退</option>
            <option value="缺勤">缺勤</option>
        </select><br>
        <button type="submit">提交</button>
    </form>
    <h2>异常情况</h2>
    <table>
        <tr>
            <th>姓名</th>
            <th>日期</th>
            <th>考勤状态</th>
        </tr>
        <?php
            // PHP代码
        ?>
    </table>
</body>
</html>

Back-end data processing

In the page, we submit employee attendance information to a file called analyze. Data processing and analysis are performed in the back-end processing script of php. The following is a simple back-end script example:

<?php
// 连接数据库
$conn = mysqli_connect('localhost', 'root', 'password', 'attendance');

// 获取表单提交的数据
$name = $_POST['name'];
$date = $_POST['date'];
$status = $_POST['status'];

// 将考勤信息插入数据库
$insertQuery = "INSERT INTO records (`name`, `date`, `status`) VALUES ('$name', '$date', '$status')";
$result = mysqli_query($conn, $insertQuery);

if ($result) {
    echo "考勤信息插入成功";
} else {
    echo "考勤信息插入失败";
}

// 查询异常情况
$query = "SELECT * FROM records WHERE `status` != '正常' ORDER BY `date` DESC";
$result = mysqli_query($conn, $query);

while ($row = mysqli_fetch_assoc($result)) {
    echo "<tr>";
    echo "<td>".$row['name']."</td>";
    echo "<td>".$row['date']."</td>";
    echo "<td>".$row['status']."</td>";
    echo "</tr>";
}

// 关闭数据库连接
mysqli_close($conn);
?>

In the above code, we first connect to the database, then obtain the submitted form data and insert the attendance information into the database. Then, we query the database for records of exceptions and display the results in a table on the page.

Deployment and Usage

Upload the front-end pages and back-end scripts to the server, and ensure that PHP and MySQL are installed on the server. Then, open the browser, visit the front-end page, enter employee attendance information and submit. Exceptions will be displayed on the page.

Summary

Write an employee attendance exception analysis tool through PHP, which can analyze and handle employee attendance situations conveniently and quickly. By properly designing the database and front-end pages, and writing corresponding back-end processing scripts, we can implement a powerful and practical employee attendance exception analysis tool. I hope the above code examples and steps are helpful to you.
