thinkPHP导出csv文件及用表格输出excel的方法

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;
     }
    }

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>   

    <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>


    <input id="submit" type="submit" value="Run »">
    </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。

希望本文所述对大家基于thinkPHP框架的php程序设计有所帮助。
