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。
