php mysql怎么编写视频网站

CREATE TABLE videos (
    id INT AUTO_INCREMENT PRIMARY KEY,
    title VARCHAR(255) NOT NULL,
    description TEXT,
    url VARCHAR(255) NOT NULL,
    uploaded_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP
);

<?php
// 数据库连接信息
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "video_db";

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

// 检查连接
if ($conn->connect_error) {
    die("连接失败: " . $conn->connect_error);
}

// 查询视频信息
$sql = "SELECT id, title, description, url, uploaded_at FROM videos";
$result = $conn->query($sql);

if ($result->num_rows > 0) {
    // 输出数据
    while($row = $result->fetch_assoc()) {
        echo "ID: " . $row["id"]. " - 标题: " . $row["title"]. " - 描述: " . $row["description"]. " - 链接: " . $row["url"]. " - 上传时间: " . $row["uploaded_at"]. "<br>";
    }
} else {
    echo "0 结果";
}
$conn->close();
?>
