To create a .CSV file with syntax suitable for EXCEL you can use basic SQL:

要使用适合 EXCEL 的语法创建 .CSV 文件，您可以使用基本 SQL：

SELECT * FROM mytable
INTO OUTFILE '/mytable.csv'
FIELDS ESCAPED BY '""'
TERMINATED BY ','
ENCLOSED BY '"'
LINES TERMINATED BY '\r\n';

See the manual here.

请参阅此处的手册。

I have searched so much for this on google, but the only code that is simple and IS WORKING is the one below. Create a downloadxls.php file (or name it whatever.php), copy/paste the code below, complete the host, username, password, database and table sections at the beginning of the code, and there you have a very nice working code. Then load the php file in your browser, and the xls file will be downloaded. I've tried it, and I'm using it.

我在谷歌上为此搜索了很多，但唯一简单且有效的代码是下面的代码。创建一个 downloadxls.php 文件（或将其命名为whatever.php），复制/粘贴下面的代码，完成代码开头的主机、用户名、密码、数据库和表部分，然后你就有了一个非常好的工作代码. 然后在浏览器中加载 php 文件，就会下载 xls 文件。我试过了，我正在使用它。

All the best :)

祝一切顺利 ：）

I think this is what you are looking for

我想这就是你要找的

You can create your own file by checking this address: http://www.programmingfacts.com/export-mysql-data-into-excelcsv-via-php/

您可以通过检查此地址来创建自己的文件：http: //www.programmingfacts.com/export-mysql-data-into-excelcsv-via-php/

I can't add working code in here sth is wrong =/

我不能在这里添加工作代码……这是错误的 =/

but make all \\t to \t and all \\n to \n

但让所有 \\t 到 \t 和所有 \\n 到 \n

If you want to use PHP, consider the fputcsvfunction. But you can export from MySQL to text format without PHP. See this pageon using mysqldump.

如果要使用 PHP，请考虑fputcsv函数。但是您可以在没有 PHP 的情况下从 MySQL 导出为文本格式。有关使用 mysqldump 的信息，请参阅此页面。

Add Export button:

添加导出按钮：

<button  type="button" class="btn btn-warning btn-sm" onClick="tableToExcel('testTable', 'W3C Example Table')"   title="Export to Excel">Export</button></div><br/>

Add id to table:

将 id 添加到表中：

<table class="table table-bordered table-hover " border="1" id="testTable" >

Add script at below of body:

在正文下方添加脚本：

<script type="text/javascript"> 
    var tableToExcel = (function() {
              var uri = 'data:application/vnd.ms-excel;base64,'
              , template = '<html xmlns:o="urn:schemas-microsoft-com:office:office" xmlns:x="urn:schemas-microsoft-com:office:excel" xmlns="http://www.w3.org/TR/REC-html40"><head><!--[if gte mso 9]><xml><x:ExcelWorkbook><x:ExcelWorksheets><x:ExcelWorksheet><x:Name>{worksheet}</x:Name><x:WorksheetOptions><x:DisplayGridlines/></x:WorksheetOptions></x:ExcelWorksheet></x:ExcelWorksheets></x:ExcelWorkbook></xml><![endif]--></head><body><table>{table}</table></body></html>'
              , base64 = function(s) { return window.btoa(unescape(encodeURIComponent(s))) }
              , format = function(s, c) { return s.replace(/{(\w+)}/g, function(m, p) { return c[p]; }) }
              return function(table, name) {
                if (!table.nodeType) table = document.getElementById(table)
                  var ctx = {worksheet: name || 'Worksheet', table: table.innerHTML}
                window.location.href = uri + base64(format(template, ctx))

Try the fputcsv function. Also the MySql CE (5.2) Workbench is a good tool for both exporting the data and getting a picture of the database as a diagram.

试试 fputcsv 函数。MySql CE (5.2) Workbench 也是一个很好的工具，用于导出数据和获取数据库图片作为图表。

All thanks to Linmic and @Kaszoni Ferencz for sharing this. Nothing more then updated to PDO as mysql functions no more available.

感谢 Linmic 和 @Kaszoni Ferencz 分享这一点。由于 mysql 功能不再可用，因此仅更新到 PDO。

// Author: Linmic, email: [email protected]
// Updated By: Najm
$host = ""; // your db host (ip/dn)
$user = ""; // your db's privileged user account
$password = ""; // and it's password

$table_name = "";// table name of the selected db
$skip_column=[];// skip any column not needed in excel    
$db = new PDO("mysql:host=$host;dbname=$db_name;charset=utf8","$user","$password",[PDO::ATTR_PERSISTENT => true]);
