PHP中导出Excel，将数据以Excel形式导出

现在，很多地方都需要导出数据，这里说一种简单的方法将数据以Excel的形式导出，方法如下：

 <?php
     date_default_timezone_set('PRC');//设置时区

     /*设置head头信息*/
     Header("Content-Type:application/vnd.ms-excel;charset=UTF-8");
     Header("Accept-Ranges:bytes");
     Header("Content-Disposition:attachment;filename=".date('YmdHis').".xls");
     Header("Pragma:no-cache");
     Header("Expires:0");

     $str = $str2 = null;
     /*设置表格信息*/
     $str.= "ID"."\t";
     $str.= "用户名"."\t";
     $str.= "密码"."\t";
     $str.= "邮箱"."\t\r\n";
     $info = iconv("UTF-8","GBK",$str);
     echo $info;

     /*查询内容导出数据库数据*/
     $link = @mysql_connect('localhost','root','') or die('Failed to connect to the MySQL');
     mysql_select_db('l_test',$link);
     mysql_set_charset('utf8',$link);
     $query = 'select * from lt_user';
     $result = mysql_query($query);
     while($row = mysql_fetch_assoc($result)){
         $list[] = $row;
     }
     mysql_free_result($result);
     mysql_close($link);

     foreach($list as $v){
         $str2.= trim(iconv("UTF-8","GBK",$v['id']))."\t";
         $str2.= trim(iconv("UTF-8","GBK",$v['username']))."\t";
         $str2.= trim(iconv("UTF-8","GBK",$v['passwd']))."\t";
         $str2.= trim(iconv("UTF-8","GBK",$v['email']))."\t\r\n";
     }
     echo $str2;
 ?> 

这个方法相对简单，但在一些小的程序上，作为一个简单的方法还是不错的，希望能对大家有所帮助。
