php添加友情链接的代码（快速实现网站友情链接功能）
## 一、创建数据库表
```sql
CREATE TABLE links (
id INT AUTO_INCREMENT PRIMARY KEY,
name VARCHAR(50) NOT NULL,
url VARCHAR(255) NOT NULL,
description TEXT
```php
// 连接数据库
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "dbname";
$conn = new mysqli($servername, $username, $password, $dbname);
// 检查连接是否成功
if ($conn->connect_error) {
die("连接失败: " . $conn->connect_error);
// 处理表单数据
if ($_SERVER["REQUEST_METHOD"] == "POST") {
$name = $_POST["name"];
$url = $_POST["url"];
$description = $_POST["description"];
// 插入数据到数据库
$sql = "INSERT INTO links (name, url, description) VALUES ('$name', '$url', '$description')";
if ($conn->query($sql) === TRUE) {
} else {
echo "Error: " . $sql . "
" . $conn->error;
}
// 关闭数据库连接
$conn->close();
```php
// 连接数据库
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "dbname";
$conn = new mysqli($servername, $username, $password, $dbname);
// 检查连接是否成功
if ($conn->connect_error) {
die("连接失败: " . $conn->connect_error);
$sql = "SELECT * FROM links";
$result = $conn->query($sql);
if ($result->num_rows > 0) {
// 输出数据
while($row = $result->fetch_assoc()) {
echo "" . $row["name"] . "
";
echo $row["description"] . "
";
}
} else {
echo "0 个结果";
// 关闭数据库连接
$conn->close();
