PHP development of enterprise resource planning (ERP) systems that build human resource management functions

PHP development to build an enterprise resource planning (ERP) system with human resource management functions

Introduction:
As the scale of enterprises continues to expand, human resource management becomes more and more complex. Traditional human resource management methods can no longer meet the needs of enterprises, so enterprise resource planning (ERP) systems have become an indispensable tool for managers. This article will introduce how to use PHP to develop an enterprise resource planning system with human resources management functions, and attach relevant code examples.

1. System architecture design

1. Database design
   First of all, we need to design a suitable database structure to store human resources-related data. The following is a sample table structure:

CREATE TABLE employees (
    id INT AUTO_INCREMENT PRIMARY KEY,
    name VARCHAR(100) NOT NULL,
    department VARCHAR(100) NOT NULL,
    position VARCHAR(100),
    salary INT,
    hire_date DATE
);

CREATE TABLE leave_requests (
    id INT AUTO_INCREMENT PRIMARY KEY,
    employee_id INT NOT NULL,
    start_date DATE NOT NULL,
    end_date DATE NOT NULL,
    status ENUM('pending', 'approved', 'rejected') DEFAULT 'pending',
    FOREIGN KEY (employee_id) REFERENCES employees(id)
);

CREATE TABLE performance_reviews (
    id INT AUTO_INCREMENT PRIMARY KEY,
    employee_id INT NOT NULL,
    review_date DATE,
    feedback TEXT,
    FOREIGN KEY (employee_id) REFERENCES employees(id)
);

2. System Function Design
   Next, we need to determine the functions required by the system. In terms of human resources management, some common functions include employee information management, leave management, and performance evaluation management. We add the following functions to the system:

• Add employee information: New employee information can be added to the database.
• Update employee information: You can update employee department, position, salary and other information.
• Leave Approval: Can handle employees' leave applications, including approving and rejecting leave requests.
• Performance Appraisal: Can conduct performance appraisals for employees and provide corresponding feedback.

2. System Development

1. Employee Information Management
   First, we need to create a page to add and update employee information. The following is a simple sample code:

<?php
// 添加员工信息
if (isset($_POST['add_employee'])) {
    $name = $_POST['name'];
    $department = $_POST['department'];
    $position = $_POST['position'];
    $salary = $_POST['salary'];
    $hire_date = $_POST['hire_date'];

    // 将员工信息插入数据库
    // ...

    echo "员工信息添加成功！";
}

// 更新员工信息
if (isset($_POST['update_employee'])) {
    $id = $_POST['id'];
    $department = $_POST['department'];
    $position = $_POST['position'];
    $salary = $_POST['salary'];

    // 更新员工信息
    // ...

    echo "员工信息更新成功！";
}
?>

<form method="post">
    <label>姓名:</label>
    <input type="text" name="name">

    <label>部门:</label>
    <input type="text" name="department">

    <label>职位:</label>
    <input type="text" name="position">

    <label>工资:</label>
    <input type="text" name="salary">

    <label>入职日期:</label>
    <input type="date" name="hire_date">

    <button type="submit" name="add_employee">添加员工</button>
    <button type="submit" name="update_employee">更新员工信息</button>
</form>

2. Leave Management
   Next, we add the function of leave management. The following is a simple sample code:

<?php
// 处理请假请求
if (isset($_POST['submit_leave'])) {
    $employee_id = $_POST['employee_id'];
    $start_date = $_POST['start_date'];
    $end_date = $_POST['end_date'];

    // 将请假请求插入数据库
    // ...

    echo "请假请求已提交！";
}
?>

<form method="post">
    <input type="hidden" name="employee_id" value="1">

    <label>开始日期:</label>
    <input type="date" name="start_date">

    <label>结束日期:</label>
    <input type="date" name="end_date">

    <button type="submit" name="submit_leave">提交请假请求</button>
</form>

3. Performance Evaluation Management
   Finally, we add the function of performance evaluation. The following is a simple sample code:

<?php
// 提交绩效评估
if (isset($_POST['submit_review'])) {
    $employee_id = $_POST['employee_id'];
    $review_date = $_POST['review_date'];
    $feedback = $_POST['feedback'];

    // 将绩效评估插入数据库
    // ...

    echo "绩效评估已提交！";
}
?>

<form method="post">
    <input type="hidden" name="employee_id" value="1">

    <label>评估日期:</label>
    <input type="date" name="review_date">

    <label>反馈意见:</label>
    <textarea name="feedback"></textarea>

    <button type="submit" name="submit_review">提交绩效评估</button>
</form>

3. Summary
By using PHP development, we can quickly build an enterprise resource planning system with human resource management functions. This article introduces the architectural design of the system and provides some sample code to implement some functions. Of course, you can expand and optimize your system based on these sample codes based on actual needs.

Through this ERP system, managers can better manage and monitor the company's human resources, improve work efficiency, and provide employees with a better work experience. At the same time, it also provides accurate data support for corporate decision-making. I hope this article can provide some help to your corporate human resources management.
