thinkphp导出csv文件，用表格输出excel

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);
            $out = '<table class="data_table"><tr><th>email</th><th>firstname</th><th>lastname</th></tr>';
            while($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);
            $out = '<table class="data_table"><tr><th>email</th></tr>';
            while($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 name="frm" method="get" action="purchase_prospects.php">
<strong>Select Site:</strong> 
<select name="site_id" id="site_id">
    <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 id="customer_type" name="customer_type">
    <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 id="submit" 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。
