php友情链接表如何做

<code class="sql">CREATE DATABASE my_database;
USE my_database;
CREATE TABLE links (
  id INT NOT NULL AUTO_INCREMENT,
  name VARCHAR(255) NOT NULL,
  url VARCHAR(255) NOT NULL,
  PRIMARY KEY (id)
);</code>

<code class="php">$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "my_database";

// 创建连接
$conn = mysqli_connect($servername, $username, $password, $dbname);

// 检测连接
if (!$conn) {
  die("连接失败: " . mysqli_connect_error());
}</code>

<code class="php">$name = "Google";
$url = "https://www.google.com";

$sql = "INSERT INTO links (name, url) VALUES ('$name', '$url')";

if (mysqli_query($conn, $sql)) {
  echo "友情链接已添加";
} else {
  echo "错误: " . mysqli_error($conn);
}</code>

<code class="php">$sql = "SELECT * FROM links";
$result = mysqli_query($conn, $sql);

if (mysqli_num_rows($result) > 0) {
  // 输出友情链接
  while($row = mysqli_fetch_assoc($result)) {
    echo "<a href='" . $row['url'] . "'>" . $row['name'] . "</a><br>";
  }
} else {
  echo "没有友情链接";
}</code>

<code class="php">mysqli_close($conn);</code>
