通过 php 将 MYSQL 数据导出到 Excel/CSV

Question

我想通过 php 将 MYSQL 数据导出到 Excel/CSV。以便我以后可以使用我的数据库，或者有人可以使用和理解它。

Answer 1

如果您想使用 PHP，请考虑使用 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。使用 mysqldump 见this page。

Answer 2

试试 fputcsv 函数。此外，MySql CE (5.2) Workbench 是一个很好的工具，既可以导出数据，也可以以图表形式获取数据库的图片。

Answer 3

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';

参见手册here。

Answer 4

我想这就是你要找的东西

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

我不能在这里添加工作代码……这是错误的 =/

但将所有 \\t 设为 \t 并将所有 \\n 设为 \n

Answer 6

我在谷歌上搜索了很多，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，数据库和表格部分，你有一个非常好的工作代码.然后在浏览器中加载php文件，xls文件将被下载。我试过了，我正在使用它。

一切顺利:)

Answer 7

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/>

给表添加id：

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

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))
              }
            })()</script>

感谢 Linmic 和 @Kaszoni Ferencz 的分享。由于 mysql 功能不再可用，因此更新为 PDO 仅此而已。

// Author: Linmic, email: linmicya@gmail.com
// Updated By: Najm
$host = ""; // your db host (ip/dn)
$user = ""; // your db's privileged user account
$password = ""; // and it's password
$db_name = ""; // db name
$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]);

$export = $db->query("DESCRIBE $table_name"); 
$fields = $export->fetchAll(PDO::FETCH_COLUMN);
$columns = "";
foreach($fields as $v)
{
    if(in_array($v,$skip_column)) continue;
