PHP将Excel导入数据库以及数据库数据导出至Excel

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)

<?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        */     }  ?>        
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Http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:

<?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";}?>
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。

Explain secure password hashing in PHP (e.g., password_hash, password_verify). Why not use MD5 or SHA1? Explain secure password hashing in PHP (e.g., password_hash, password_verify). Why not use MD5 or SHA1? Apr 17, 2025 am 12:06 AM

In PHP, password_hash and password_verify functions should be used to implement secure password hashing, and MD5 or SHA1 should not be used. 1) password_hash generates a hash containing salt values ​​to enhance security. 2) Password_verify verify password and ensure security by comparing hash values. 3) MD5 and SHA1 are vulnerable and lack salt values, and are not suitable for modern password security.
