How to implement employee leave management function through PHP?

Employee leave management is an important function in an enterprise. Effectively managing employees' leave applications can improve the company's work efficiency and employees' work enthusiasm. As a popular server-side scripting language, PHP is loved by developers because of its ease of learning, ease of use and flexibility. Through PHP, we can quickly implement employee leave management functions.

The following will introduce how to write an employee leave management system through PHP and provide specific code examples.

1. Database design

First, we need to design a database to store employees' leave information. Create a database named "leave_management" and create a table named "leave_requests" in it. The table should contain the following fields:

• id (auto-increment primary key)
• employee_name (employee name)
• leave_type (leave type)
• leave_start_date (leave start date)
• leave_end_date (leave end date)
• leave_reason (leave reason)
• status (leave status, such as pending approval, approved, rejected )

2. Create a leave application form

Create a leave application form on the web page to collect employees' leave information. The following is a simple example:

  员工姓名:
  
  
  请假类型:
  
    病假
    事假
    年假
  
  
  请假开始日期:
  
  
  请假结束日期:
  
  
  请假原因:
  
  
  

3. Processing leave requests

Next, we create a file called "process_leave.php" for processing employee requests Leave application. In this file we will get the various fields from the form and insert them into the database.

4. Display leave information

In the web page, we can create a page to display employee leave information. The following is a simple example:

 0) {
  while ($row = mysqli_fetch_assoc($result)) {
    echo "员工姓名: " . $row['employee_name'] . "
";
    echo "请假类型: " . $row['leave_type'] . "
";
    echo "请假开始日期: " . $row['leave_start_date'] . "
";
    echo "请假结束日期: " . $row['leave_end_date'] . "
";
    echo "请假原因: " . $row['leave_reason'] . "
";
    echo "请假状态: " . $row['status'] . "

";
  }
} else {
  echo "暂无请假申请";
}

// 关闭数据库连接
mysqli_close($conn);
?>

Through the above steps, we can implement a basic employee leave management function through PHP. When an employee submits a leave application, his or her leave information will be inserted into the database and can be viewed through another page.

Of course, we can expand and improve this basic system according to actual needs, such as adding approval functions, employee login restrictions, etc. I hope the code examples in this article can help you better understand how to implement employee leave management functions through PHP.
