Application of employee information management module developed using PHP in enterprise resource planning (ERP) system

With the expansion of enterprise scale and the complexity of business processes, enterprise resource planning (ERP) systems are in modern is becoming increasingly important in business. As a comprehensive management system, ERP can centrally manage various resources of an enterprise, including human resources. The employee information management module is an important part of the ERP system. Through this module, employees' basic information, work records, attendance, salary and other data can be efficiently managed and collected. This article will introduce how to use PHP to develop a simple employee information management module and apply it to an enterprise resource planning (ERP) system.

First, we need to create a database for the employee information management module, which contains employee basic information, work records, attendance, salary and other data. The following is a simplified database table structure example:

Employee table (employees):

• id: employee ID (primary key)
• name: employee name
• gender：gender
• age：age
• department：department
• position：position

Work record table (work_records):

• id: record ID (primary key)
• employee_id: employee ID (foreign key, associated employee table)
• date: date
• start_time : Working time
• end_time: Working time
• duration: Working hours

Attendance table (attendance):

• id: record ID (primary key)
• employee_id: employee ID (foreign key, associated employee table)
• date: date
• status: attendance status (late, early leave, normal, etc.)

Salary table (salary):

• id: record ID (primary key)
• employee_id: employee ID (foreign key, associated employee table)
• date: date
• amount: salary amount

In PHP, we can use database operation extensions (such as mysqli or PDO) to interact with the MySQL database. The following is an example of a basic employee information management module:

1. Add employee information

<?php
// 连接数据库
$servername = "localhost";
$username = "root";
$password = "password";
$database = "erp";

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

// 处理表单提交
if ($_SERVER["REQUEST_METHOD"] == "POST") {
    $name = $_POST["name"];
    $gender = $_POST["gender"];
    $age = $_POST["age"];
    $department = $_POST["department"];
    $position = $_POST["position"];

    // 插入员工信息
    $sql = "INSERT INTO employees (name, gender, age, department, position)
    VALUES ('$name', '$gender', $age, '$department', '$position')";

    if ($conn->query($sql) === TRUE) {
        echo "员工信息添加成功";
    } else {
        echo "添加失败: " . $conn->error;
    }
}

$conn->close();
?>

2. View employee information

<?php
// 连接数据库
$servername = "localhost";
$username = "root";
$password = "password";
$database = "erp";

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

// 查询员工信息
$sql = "SELECT * FROM employees";
$result = $conn->query($sql);

if ($result->num_rows > 0) {
    // 输出数据
    while ($row = $result->fetch_assoc()) {
        echo "ID: " . $row["id"] . "<br>";
        echo "姓名: " . $row["name"] . "<br>";
        echo "性别: " . $row["gender"] . "<br>";
        echo "年龄: " . $row["age"] . "<br>";
        echo "部门: " . $row["department"] . "<br>";
        echo "职位: " . $row["position"] . "<br><br>";
    }
} else {
    echo "没有员工信息";
}

$conn->close();
?>

Pass In the above code example, we can add and view employee information. In practical applications, the employee information management module can be further improved, including functions such as editing and deleting employee information, and exporting employee data. In addition, it can be combined with other modules, such as attendance module and salary calculation module, to achieve more comprehensive employee information management and statistical functions.

Summary:

The application of the employee information management module in the enterprise resource planning (ERP) system is crucial, and can help companies efficiently manage and count employees’ basic information, work records, and attendance and salary and other key data. By using the employee information management module developed in PHP, we can flexibly implement operations such as adding, deleting, modifying, and checking employee information, and can integrate with other modules to further improve the enterprise's management efficiency and data accuracy.
