HomeBackend DevelopmentPHP TutorialPHP将Excel导入数据库及数据库数据导出至Excel的方法_PHP

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;>    

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

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;>

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。

How does PHP type hinting work, including scalar types, return types, union types, and nullable types?How does PHP type hinting work, including scalar types, return types, union types, and nullable types?Apr 17, 2025 am 12:25 AM

PHP type prompts to improve code quality and readability. 1) Scalar type tips: Since PHP7.0, basic data types are allowed to be specified in function parameters, such as int, float, etc. 2) Return type prompt: Ensure the consistency of the function return value type. 3) Union type prompt: Since PHP8.0, multiple types are allowed to be specified in function parameters or return values. 4) Nullable type prompt: Allows to include null values ​​and handle functions that may return null values.
