使用php和mysql获取并存储根目录和文件

$rootDirectory = $_SERVER['DOCUMENT_ROOT'];

$files = scandir($rootDirectory);

// 连接到MySQL数据库
$servername = "数据库服务器地址";
$username = "数据库用户名";
$password = "数据库密码";
$dbname = "数据库名";

$conn = new mysqli($servername, $username, $password, $dbname);

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

// 插入文件信息到表中
foreach ($files as $file) {
    $sql = "INSERT INTO files (filename) VALUES ('$file')";
    if ($conn->query($sql) === TRUE) {
        echo "文件信息插入成功";
    } else {
        echo "错误: " . $sql . "<br>" . $conn->error;
    }
}

// 关闭数据库连接
$conn->close();
