我想通过php将MYSQL数据导出到Excel / CSV。这样我以后可以使用我的数据库，或者有人可以使用和理解它。
答案 0 :(得分：15)
要创建具有适合EXCEL语法的.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';
请参阅手册here。

我在google上搜索过这么多内容，但是唯一简单且工作正常的代码就是下面的代码。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，在代码的开头填写主机，用户名，密码，数据库和表格部分，并且你有一个非常好的工作代码。然后在浏览器中加载php文件，下载xls文件。我试过了，我正在使用它。
一切顺利：）

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/>
向表中添加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>'

, format = function(s, c) { return s.replace(/{(\w+)}/g, function(m, p) { return c[p]; }) }
return function(table, name) {

var ctx = {worksheet: name || 'Worksheet', table: table.innerHTML}
window.location.href = uri + base64(format(template, ctx))

尝试fputcsv功能。此外，MySql CE（5.2）Workbench是一个很好的工具，可以导出数据并以图表的形式获取数据库的图片。
