CREATE TABLE articles (
  id INT(11) UNSIGNED AUTO_INCREMENT PRIMARY KEY,
  title VARCHAR(255) NOT NULL,
  content TEXT NOT NULL,
  likes INT(11) UNSIGNED DEFAULT 0
);

// 链接到数据库
$conn = mysqli_connect('host', 'username', 'password', 'database_name');
// 获取文章ID
$id = $_GET['id'];
// 查询文章
$sql = "SELECT * FROM articles WHERE id = $id";
$result = mysqli_query($conn, $sql);
// 如果查询失败，则输出错误消息并终止脚本
if (!$result) {
  die("Error: " . mysqli_error());
}
// 如果找不到文章，则输出错误消息并退出
if (mysqli_num_rows($result) == 0) {
  echo "Article not found";
}
// 根据文章id从数据库中获取点赞数
$sql = "SELECT likes FROM articles WHERE id = $id";
$result = mysqli_query($conn, $sql);
$row = mysqli_fetch_assoc($result);
$likes = $row['likes'];
// 输出文章标题、正文和点赞数
echo "<h1>" . $article[&#39;title&#39;] . "</h1>";
echo "<p>" . $article[&#39;content&#39;] . "</p>";
echo "<p>Likes: " . $likes . "</p>";
// 显示点赞按钮
echo "<form action=&#39;like.php?id=" . $id . "&#39; method=&#39;post&#39;>";
echo "<button type=&#39;submit&#39; name=&#39;like&#39;>Like</button>";
