本文实例讲述了thinkPHP导出csv文件及用表格输出excel的方法。分享给大家供大家参考，具体如下：
1.thinkphp导出csv文件
导出csv文件可能就那几行代码，今天有个问题困扰我好久，就是导出之后出现一些html代码，这个不应该，view里面是空的，controller中最后也没有$this->display()，最后细心看到think_page_trace这样的字样，恍然大悟，是页面的跟踪日志，这个默认是会输出来的。最后在方法后面加了一个exit结束就好了，下面是代码：
1.IndexController.class.php

<?php
namespace Home\Controller;
use Think\Controller;
class IndexController extends Controller {
public function index(){
$hotel = M('keywords')->field('PageName,Page')->select();
$str = "关键字,名称\n";
$str = iconv('utf-8','gb2312',$str);
$result = mysql_query("select PageName,Page from hotel_keywords");
while($row=mysql_fetch_array($result)){
$PageName = iconv('utf-8','gb2312',$row['PageName']);
$Page = iconv('utf-8','gb2312',$row['Page']);
$str .= $PageName.",".$Page."\n";
}
$fileName = date('Ymd').'.csv';
$model = D('Keywords');
$model->export_csv($fileName,$str);
exit;
}
}

use Think\Model;
class KeywordsModel extends Model{
public function export_csv($filename, $data){
header("Content-type:text/csv");
header("Content-Disposition:attachment;filename=".$filename);
header('Cache-Control:must-revalidate,post-check=0,pre-check=0');
header('Expires:0');
header('Pragma:public');
echo $data;
}
}

奥妙就在IndexController.class.php代码最后一句的exit这里，如果不写这句，输出的excel里面有html源码，截图如下：
2.用表格输出excel
如下代码purchase_prospects.php

这样也可以导出ecxcel文件，截图如下
依然注意最后一句exit;如果没有这一句，excel里面会有一些页面元素。
希望本文所述对大家基于thinkPHP框架的php程序设计有所帮助。
