Excel可以很方便地处理数据,数据库的数据如果能够读取成excel文件,会很方便地进行处理。

实现数据库数据到Excel的转换类excel.php

<?php
class excel
{ 
   function start()
    {
      ob_start();
     }
    function save($path)
      {
        $data = ob_get_contents();
        ob_end_clean();
        $this->wirtetoexcel($path,$data);
     }
   function wirtetoexcel ($fn,$data)
     {
       $fp=fopen($fn,"wb");
       fwrite($fp,$data);
       fclose($fp);
    }
}
?>

创建这个类的对象,再调用这个对象的方法,即可实现数据库数据导出为Excel。

<meta http-equiv="Content-Type" content="text/html; charset=utf-8">  
<link href="css/style.css" rel="stylesheet" type="text/css" />  
<?php   
include("conn.php");  
$query=mysql_query("select * from map order by register_date desc") ;   
$i=$perpagenum*($page-1)+1;   
include_once("excel.php");
$Excel=new Excel();
$Excel->start();
?>
<table width="600" border="0">  
	<tr>  
    <td align="center">companyname_cn</td>  
    <td align="center">companyname_en"</td>  
    <td align="center">name</td>  
    <td align="center">position</td>  
    <td align="center">tel</td>  
    <td align="center">fax</td>  
    <td align="center">email</td>  
    <td align="center">website</td>  
    <td align="center">product</td>  
  </tr> 
<?php
while($myrow = mysql_fetch_array($query)){   
?>  
  <tr>  
    <td align="center"><?php echo $myrow["companyname_cn"]; ?></td>  
    <td align="center"><?php echo $myrow["companyname_en"]; ?></td>  
    <td align="center"><?php echo $myrow["name"]; ?></td>  
    <td align="center"><?php echo $myrow["position"]; ?></td>  
    <td align="center"><?php echo $myrow["tel"]; ?></td>  
    <td align="center"><?php echo $myrow["fax"]; ?></td>  
    <td align="center"><?php echo $myrow["email"]; ?></td>  
    <td align="center"><?php echo $myrow["website"]; ?></td>  
    <td align="center"><?php echo $myrow["product"]; ?></td>  
  </tr>  
<? }  
?>  
</table>  
<p>  
<?php   
	$Excel->save("Excel/data.xls"); 
?>  
</p>

关键代码其实就几行:

// 包含类文件
include_once("excel.php");
// 创建excel类的对象
$Excel=new Excel();
// 调用对象 $Excel 的 start()方法
$Excel->start();
// 调用对象的 save() 声称 excel 文件。
$Excel->save("Excel/data.xls");
