Question

这是关于从Mysql表中以CSV格式重新获取数据： -

代码，我试过了： -

<?php
// mysql database connection details
    $host = "localhost";
    $username = "root";
    $password = "hello";
    $dbname = "mysql2csv";

// open connection to mysql database
    $connection = mysqli_connect($host, $username, $password, $dbname) or     die("Connection Error " . mysqli_error($connection));

// fetch mysql table rows
    $sql = "select * from tbl_books";
    $result = mysqli_query($connection, $sql) or die("Selection Error " .     mysqli_error($connection));

    $fp = fopen('books.csv', 'w');

    while($row = mysqli_fetch_assoc($result))
{
        fputcsv($fp, $row);
}

    fclose($fp);

//close the db connection
    mysqli_close($connection);

将这些行添加到您的html标题

<meta content="text/html;charset=utf-8" http-equiv="Content-Type">
<meta content="utf-8" http-equiv="encoding">

修改如果您使用的是PHP文件：

header('Content-Type: text/html; charset=utf-8');

未声明HTML文档
