本文实例讲述了PHP将Excel导入数据库及数据库数据导出至Excel的方法。分享给大家供大家参考。具体实现方法如下:

一.导入

导入需要使用能读取Excel的组件,网上也有比较好的组件,这里分享我使用的:下载  提取码:vxyn。(注意两个文件有引用关系)

<&#63;php

//传入要导入的Excel的文件名

function import_to_DB($filename) {

  require_once'reader.php';

  $data = new Spreadsheet_Excel_Reader();

  //创建读取Excel的对象

  $data->setOutputEncoding('utf-8');

  //设置读取Excel内容后输出的字符编码

  $data->read("data/Excel/{$filename}.xls");

  $db = mysql_connect('localhost', '用户名', '密码') or die("Could not connect to database.");

  //连接数据库 

  mysql_query("set names 'uft8'");

  //输出中文 

  mysql_select_db('数据库名');

  //选择数据库 

  error_reporting(E_ALL ^ E_NOTICE);

  for ($i = 1; $i <= $data->sheets[0]['numRows']; $i++) {

    echo $data->sheets[0]['cells'][$i][列数];

    //这里可以把每一行相应列的值插到数据库中,如:

    /*

    $sql="insert "表名" values(对应项...)";

    mysql_query($sql);

    可加上错误判断

    */

  }

&#63;>   

Copy after login

总之,能够读出表格中每一行中的相应列$data->sheets[0][行][列]的值,插入操作就好办了。

二.导出

导出可以利用MIME协议轻松导出表格文件,不用依赖任何组件。按如下格式设置header即可导出Excel,同时浏览器进行下载

header('Content-type: text/html; charset=utf-8');

header("Content-type:application/vnd.ms-excel;charset=UTF-8"); //application/vnd.ms-excel指定输出Excel格式

header("Content-Disposition:filename=表格文件名.xls");

//输出的表格名称

Copy after login

完整代码如下:

<&#63;php

header('Content-type: text/html; charset=utf-8');

header("Content-type:application/vnd.ms-excel;charset=UTF-8");

header("Content-Disposition:filename=表格文件名.xls");

$conn = mysql_connect("localhost","root","数据库密码") or die("不能连接数据库");

mysql_select_db("数据库名", $conn);

mysql_query("set names 'UTF-8'");

$sql="select * from 表名 where 条件";

$result=mysql_query($sql);

echo "表头1\t表头2\t表头3\n";

while($row=mysql_fetch_array($result)){

  echo $row[0]."\t".$row[1]."\t".$row[2]."\n";

}

&#63;>

Copy after login

这里其实\t就是换格,\n就是换行。在一个网页中设置这个php文件的链接,当点击时浏览器会自动把传过来的流保存为Excel文件。

希望本文所述对大家的php程序设计有所帮助。
