// 示例代码：处理评论提交的PHP文件
<?php
if ($_SERVER['REQUEST_METHOD'] == 'POST') {
    $comment = $_POST['comment'];
    $article_id = $_POST['article_id'];
    $user_name = $_POST['user_name'];

    // 数据库连接
    $conn = new mysqli('localhost', 'username', 'password', 'database_name');
    if ($conn->connect_error) {
        die("连接失败: " . $conn->connect_error);
    }

    // 插入评论
    $sql = "INSERT INTO comments (article_id, user_name, comment) VALUES ('$article_id', '$user_name', '$comment')";
    if ($conn->query($sql) === TRUE) {
        echo "评论提交成功";
    } else {
        echo "Error: " . $sql . "<br>" . $conn->error;
    }

    $conn->close();
}

// 示例代码：设置数据库连接字符集
$conn = new mysqli('localhost', 'username', 'password', 'database_name');
$conn->set_charset("utf8");
