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.

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.
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.

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);

Copy after login

}

// 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
}

Copy after login

} else {

echo "0 results";

Copy after login

}

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

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:
