数据库设计

创建数据库表结构存储人员信息，通常包括以下字段：

id：主键，自增
name：姓名
age：年龄
gender：性别
position：职位
salary：薪资
department：部门
join_date：入职日期

SQL创建表示例：

CREATE TABLE employees (
    id INT AUTO_INCREMENT PRIMARY KEY,
    name VARCHAR(100) NOT NULL,
    age INT,
    gender ENUM('Male', 'Female', 'Other'),
    position VARCHAR(100),
    salary DECIMAL(10,2),
    department VARCHAR(100),
    join_date DATE
);

连接数据库

使用PDO连接MySQL数据库：

$host = 'localhost';
$dbname = 'personnel_system';
$username = 'root';
$password = '';

try {
    $pdo = new PDO("mysql:host=$host;dbname=$dbname", $username, $password);
    $pdo->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
} catch(PDOException $e) {
    die("Connection failed: " . $e->getMessage());
}

添加人员功能

创建表单接收用户输入并插入数据库：

if ($_SERVER['REQUEST_METHOD'] == 'POST' && isset($_POST['add'])) {
    $stmt = $pdo->prepare("INSERT INTO employees (name, age, gender, position, salary, department, join_date) 
                          VALUES (:name, :age, :gender, :position, :salary, :department, :join_date)");

    $stmt->execute([
        ':name' => $_POST['name'],
        ':age' => $_POST['age'],
        ':gender' => $_POST['gender'],
        ':position' => $_POST['position'],
        ':salary' => $_POST['salary'],
        ':department' => $_POST['department'],
        ':join_date' => $_POST['join_date']
    ]);

    header("Location: index.php");
    exit();
}

显示人员列表

查询并显示所有人员信息：

$stmt = $pdo->query("SELECT * FROM employees");
$employees = $stmt->fetchAll(PDO::FETCH_ASSOC);

foreach ($employees as $employee) {
    echo "<tr>
            <td>{$employee['id']}</td>
            <td>{$employee['name']}</td>
            <td>{$employee['age']}</td>
            <td>{$employee['gender']}</td>
            <td>{$employee['position']}</td>
            <td>{$employee['salary']}</td>
            <td>{$employee['department']}</td>
            <td>{$employee['join_date']}</td>
            <td>
                <a href='edit.php?id={$employee['id']}'>Edit</a>
                <a href='delete.php?id={$employee['id']}' onclick='return confirm(\"Are you sure?\")'>Delete</a>
            </td>
          </tr>";
}

编辑人员信息

实现编辑功能需要先查询原有数据再更新：

// 查询原有数据
$stmt = $pdo->prepare("SELECT * FROM employees WHERE id = ?");
$stmt->execute([$_GET['id']]);
$employee = $stmt->fetch();

// 更新数据
if ($_SERVER['REQUEST_METHOD'] == 'POST' && isset($_POST['update'])) {
    $stmt = $pdo->prepare("UPDATE employees SET 
                          name = :name, 
                          age = :age, 
                          gender = :gender, 
                          position = :position, 
                          salary = :salary, 
                          department = :department, 
                          join_date = :join_date 
                          WHERE id = :id");

    $stmt->execute([
        ':name' => $_POST['name'],
        ':age' => $_POST['age'],
        ':gender' => $_POST['gender'],
        ':position' => $_POST['position'],
        ':salary' => $_POST['salary'],
        ':department' => $_POST['department'],
        ':join_date' => $_POST['join_date'],
        ':id' => $_POST['id']
    ]);

    header("Location: index.php");
    exit();
}

删除人员记录

实现删除功能：

if (isset($_GET['id'])) {
    $stmt = $pdo->prepare("DELETE FROM employees WHERE id = ?");
    $stmt->execute([$_GET['id']]);

    header("Location: index.php");
    exit();
}

安全注意事项

防止SQL注入：

始终使用预处理语句
对用户输入进行验证和过滤

数据验证示例：

function validateInput($data) {
    $data = trim($data);
    $data = stripslashes($data);
    $data = htmlspecialchars($data);
    return $data;
}

分页功能

实现数据分页显示：

$perPage = 10;
$page = isset($_GET['page']) ? (int)$_GET['page'] : 1;
$offset = ($page - 1) * $perPage;

$total = $pdo->query("SELECT COUNT(*) FROM employees")->fetchColumn();
$totalPages = ceil($total / $perPage);

$stmt = $pdo->prepare("SELECT * FROM employees LIMIT :offset, :perPage");
$stmt->bindParam(':offset', $offset, PDO::PARAM_INT);
$stmt->bindParam(':perPage', $perPage, PDO::PARAM_INT);
$stmt->execute();
$employees = $stmt->fetchAll(PDO::FETCH_ASSOC);

搜索功能

添加姓名搜索功能：

if (isset($_GET['search'])) {
    $search = '%' . $_GET['search'] . '%';
    $stmt = $pdo->prepare("SELECT * FROM employees WHERE name LIKE :search");
    $stmt->execute([':search' => $search]);
    $employees = $stmt->fetchAll(PDO::FETCH_ASSOC);
}

这个基础的人员管理系统包含了CRUD（创建、读取、更新、删除）功能，可以根据需要进一步扩展，如添加用户认证、权限管理、文件上传等功能。
