thinkPHP导出csv文件及用表格输出excel的方法

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; } }

2.KeywordsModel.class.php

<?php namespace Home\Model; 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

<?php require('page_header.php'); $site_id = getIfSet($_GET, 'site_id', 0); $customer_type = getIfSet($_GET, 'customer_type',0); $DB = Database::connect($site_id); if($site_id>0 && $customer_type>0){ $sql = ''; $out = ''; $short_name_array = SiteSettings::$SITE_SHORT_NAME; $short_name = $short_name_array[$site_id]; switch ($customer_type) { case '1':{ $sql = "SELECT email, CONCAT(UCASE(LEFT(firstname, 1)),SUBSTRING(firstname, 2)) AS firstname, CONCAT(UCASE(LEFT(lastname, 1)),SUBSTRING(lastname, 2)) AS lastname FROM customers WHERE site_id =$site_id AND email NOT REGEXP '.+(avanquest)|(planetart)|(novadevelop)|(qatest).+' AND email IN(SELECT a.email FROM customers a INNER JOIN orders b ON a.id=b.`customer_id` AND b.is_test=0 AND a.site_id =$site_id) AND email NOT IN (SELECT email_address FROM `newsletter_unsubscribes` WHERE site_id =$site_id);"; $res = $DB->query($sql); $out = '<table><tr><th>email</th><th>firstname</th><th>lastname</th></tr>'; while($row = mysql_fetch_array($res)){ $out .= '<tr><td>'.$row['email'].'</td><td>'.$row['firstname'].'</td><td>'.$row['lastname'].'</td></tr>'; } $short_name .= '_purchased'; break; } case '2':{ $DB->query("DROP TEMPORARY TABLE IF EXISTS tmp_purchase;"); $DB->query("CREATE TEMPORARY TABLE tmp_purchase SELECT a.email FROM customers a INNER JOIN orders b ON a.id=b.`customer_id` AND b.is_test=0 AND a.site_id =$site_id; "); $DB->query("DROP TEMPORARY TABLE IF EXISTS tmp_nopurchase;"); $DB->query("CREATE TEMPORARY TABLE tmp_nopurchase SELECT email FROM customers WHERE site_id =$site_id AND email NOT IN(SELECT email FROM tmp_purchase);"); if(9 != $site_id){ $datatype = SiteSettings::getPurchaseDataType($site_id); $DB->query("INSERT tmp_nopurchase SELECT DISTINCT email FROM triggered_email_data WHERE datatype='$datatype' AND email NOT IN(SELECT email FROM tmp_purchase);"); } $sql = "SELECT DISTINCT email FROM tmp_nopurchase WHERE email NOT REGEXP '.+(avanquest)|(planetart)|(novadevelop)|(qatest).+' AND Email REGEXP '[A-Z0-9._%-]+@[A-Z0-9.-]+\.[A-Z]{2,4}$' AND email NOT IN (SELECT email_address FROM `newsletter_unsubscribes` WHERE site_id =$site_id);"; $res = $DB->query($sql); $out = '<table><tr><th>email</th></tr>'; while($row = mysql_fetch_array($res)){ $out .= '<tr><td>'.$row['email'].'</td></tr>'; } $short_name .= '_non-purchased and signup'; break; } default: break; } $out .= '</table>'; header("Content-type:application/vnd.ms-excel"); header("Content-Disposition:filename=$short_name.xls"); echo $out; exit; } ?> <h1>Purchase Prospects Report</h1> <form method="get" action="purchase_prospects.php"> <strong>Select Site:</strong> <select> <option value="0">== select site ==</option> <option value="1">STI</option> <option value="2">PA</option> <option value="3">CW</option> <option value="6">MCC</option> <option value="9">CB</option> <option value="4">STIUK</option> <option value="8">MCCUK</option> </select> &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; <strong>Select Type:</strong> <select> <option value="0">== select type ==</option> <option value="1">purchased</option> <option value="2">non-purchased and signup</option> </select> &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; <input type="submit" value="Run &raquo;"> </form> <script type="text/javascript"> $(function(){ $("#submit").click(function(){ if('0' == $("#site_id").val() || '0' == $("#customer_type").val()){ alert('please select Site and Site'); return false; } }) }); </script>

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。
