Use PHP to develop an enterprise resource planning (ERP) system that implements employee resignation management functions

Abstract:
Employee resignation management is an important part of enterprise human resources management. In order to improve the efficiency and effectiveness of the resignation process Accuracy, this article describes how to use PHP to develop a simple enterprise resource planning (ERP) system to manage the employee turnover process. The system realizes the functions of entering employee information, submitting and reviewing resignation applications, and handling resignation procedures.

Keywords: employee turnover management, enterprise resource planning system, PHP development

1. Introduction
As enterprises develop and grow, employee turnover management has become a problem that cannot be ignored. The traditional resignation process is cumbersome and prone to errors, which seriously affects the operation of the company. In order to solve this problem, we decided to use PHP to develop an enterprise resource planning (ERP) system to automate and digitize employee turnover management.

2. System design
1. Database design
We use MySQL as the backend database and design three data tables: employee table, resignation application form and resignation process table. The employee table records the employee's basic information, including employee ID, name, department, position, etc.; the resignation application form records the employee's resignation application information, including application time, reason for resignation, etc.; the resignation process table records the resignation review process, including reviewer, reviewer, etc. Opinions etc.

2. Front-end design
We use HTML, CSS and JavaScript to implement the user interface, including the employee information entry page, resignation application submission page and resignation process review page. Users can perform corresponding operations through these pages.

3.Backend development
We use PHP as the backend development language to implement the functions of entering employee information, submitting resignation applications, and reviewing the resignation process. The following is a code example:

Employee information entry page (employee.php):

<?php
if ($_SERVER["REQUEST_METHOD"] == "POST") {
  // 获取表单数据并插入数据库
  $name = $_POST["name"];
  $department = $_POST["department"];
  $position = $_POST["position"];
 
  // 执行数据库插入操作
  $conn=mysqli_connect("localhost", "username", "password", "database");
  $sql="INSERT INTO employees (name, department, position) VALUES ('$name', '$department', '$position')";
  if(mysqli_query($conn, $sql)){
      echo "员工信息录入成功！";
  } else{
      echo "员工信息录入失败！".mysqli_error($conn);
  }
  mysqli_close($conn);
}
?>
 
<html>
<body>
  <form method="POST" action="<?php echo $_SERVER['PHP_SELF'];?>">
    <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">
    <input type="submit" value="提交">
  </form>
</body>
</html>

Resignation application submission page (resignation.php):

<?php
if ($_SERVER["REQUEST_METHOD"] == "POST") {
  // 获取表单数据并插入数据库
  $employee_id = $_POST["employee_id"];
  $reason = $_POST["reason"];
 
  // 执行数据库插入操作
  $conn=mysqli_connect("localhost", "username", "password", "database");
  $sql="INSERT INTO resignations (employee_id, reason) VALUES ('$employee_id', '$reason')";
  if(mysqli_query($conn, $sql)){
      echo "离职申请提交成功！";
  } else{
      echo "离职申请提交失败！".mysqli_error($conn);
  }
  mysqli_close($conn);
}
?>
 
<html>
<body>
  <form method="POST" action="<?php echo $_SERVER['PHP_SELF'];?>">
    <label>员工ID:</label><input type="text" name="employee_id">
    <label>离职原因:</label><input type="text" name="reason">
    <input type="submit" value="提交">
  </form>
</body>
</html>

Copy after login

Resignation process review page ( approval.php):

<?php
if ($_SERVER["REQUEST_METHOD"] == "POST") {
  // 获取表单数据并更新数据库
  $resignation_id = $_POST["resignation_id"];
  $approver = $_POST["approver"];
  $comment = $_POST["comment"];
 
  // 执行数据库更新操作
  $conn=mysqli_connect("localhost", "username", "password", "database");
  $sql="UPDATE resignations SET approver='$approver', comment='$comment' WHERE id='$resignation_id'";
  if(mysqli_query($conn, $sql)){
      echo "离职流程审核成功！";
  } else{
      echo "离职流程审核失败！".mysqli_error($conn);
  }
  mysqli_close($conn);
}
?>
 
<html>
<body>
  <form method="POST" action="<?php echo $_SERVER['PHP_SELF'];?>">
    <label>离职申请ID:</label><input type="text" name="resignation_id">
    <label>审核人:</label><input type="text" name="approver">
    <label>审核意见:</label><input type="text" name="comment">
    <input type="submit" value="提交">
  </form>
</body>
</html>

3. System testing and use
We test the system by deploying the system, entering employee information, submitting resignation applications and reviewing the resignation process. After testing, the system can successfully complete the entry of employee information, submission of resignation applications, and review of the resignation process, with good results.

Conclusion:
This article uses PHP to develop and implement a simple enterprise resource planning (ERP) system with employee turnover management functions. Through the combination of front-end and back-end technologies, the system realizes the entry of employee information, the submission of resignation applications and the review of the resignation process. The system is simple and convenient to use and can improve the efficiency and accuracy of employee resignation management.

Explain JSON Web Tokens (JWT) and their use case in PHP APIs. Apr 05, 2025 am 12:04 AM

JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,
