How to combine PHP and Vue to realize the late and early departure statistics function of employee attendance

In modern enterprise management, attendance management is a very important task. In order to efficiently count employee attendance, we can use PHP and Vue to implement the late arrival and early departure statistics function. The following will introduce how to use these two tools to build a simple attendance management system and provide specific code examples.

1. Preparation
   Before starting, you first need to make sure that you have installed PHP and Vue development environment. You can download it from the official website and follow the instructions to install it.
2. Database Design
   The core of the attendance management system is the design of the database. We can create a table named "attendance", containing the following fields:

• id: the unique identifier of the attendance record
• employee_id: the unique identifier of the employee
• date: Attendance date
• in_time: Punch-in time at work
• out_time: Punch-in time at get off work

You can add it to the table according to actual needs Other fields, such as employee name, department, etc.

3. Backend development
   Use PHP to handle backend logic. First, you need to connect to the database and write some basic addition, deletion, modification and query operations. Here is a simple PHP code example:

$servername = "localhost";
$username = "your_username";
$password = "your_password ";
$dbname = "your_database";

// Create a database connection
$conn = new mysqli($servername, $username, $password, $dbname);
if ( $conn->connect_error) {

die("Connection failed: " . $conn->connect_error);

}

// Query attendance records
$sql = "SELECT * FROM attendance";
$result = $conn-> ;query($sql);

// Process query results
if ($result->num_rows > 0) {

while($row = $result->fetch_assoc()) {
    // 处理每一条记录
}

} else {

echo "0 results";

}

//Close the database connection
$conn->close();
?>

4. Front-end development
   Use Vue to build the front-end interface, and interact with the backend through AJAX requests for data. The following is a simple Vue code example:

<script><br>export default {<br> data() {</script>

return {
  attendanceData: []
};

},
mounted() {

this.fetchAttendanceData();

},
methods: {

fetchAttendanceData() {
  // 发起AJAX请求获取考勤数据
  axios.get('/api/attendance')
    .then(response => {
      this.attendanceData = response.data;
    })
    .catch(error => {
      console.log(error);
    });
}

}
};

5. Data display and statistics
   In the Vue code, we use a table to display attendance records. Trigger the AJAX request by calling the fetchAttendanceData() method and render the returned data to the page.

In the PHP code, we obtain attendance records from the database through SQL query statements and process each record through a loop.

For statistics on late arrivals and early departures, relevant logic can be added to the PHP loop to calculate the number of late arrivals and early departures by comparing the start and end time with the specified time.

To sum up, by combining PHP and Vue, we can realize the late and early departure statistics function of employee attendance. Through database design and back-end development, we can obtain employee attendance data and process it accordingly, and then use Vue to build a front-end interface for data display and statistics. I hope the above code examples and explanations are helpful to you and help you build a simple attendance management system.
