php下载文件：header（） [英] php download file: header()

问题描述

我需要一些教育。
在每个月的月底，我想从我的网络服务器上下载一些数据到我的本地PC。
所以，我已经为此写了一个脚本，它从DB中选择数据。
接下来，我想下载它。
我试过这个：

  $ file = $ month。 '。文本'; 
 $ handle = fopen（$ file，w）; 
 header（Content-Type：application / text）; 
 header（Content-Disposition：attachment，filename =。$ month。'.txt'）; 
 while（$ row = mysql_fetch_array（$ res））
 {
 $ writestring = $ row ['data_I_want']。 \r\\\
; 
 fwrite（$ handle，$ writestring）; 
} 
 fclose（$ handle）; 
  

如果我运行这个，那么该文件会被创建，但是我的文件不包含数据我想要。相反，我从我的浏览器中的HTML文件中获得了一个转储。
我在做什么错误..
谢谢，

  //下面是在哪里你创建特定月份的文本文件
 $ file = $ month。 '。文本'; 
 $ handle = fopen（$ file，w）; 
 while（$ row = mysql_fetch_array（$ res））{
 $ writestring = $ row ['data_I_want']。 \r\\\
; 
 fwrite（$ handle，$ writestring）; 
} 
 fclose（$ handle）; 
 //现在文件准备好来自数据库
 
的数据//下面添加下载文本文件
 $ filename = $ file; //文件名
 $ filepath = $ file; //文件的位置。因为你的文件是在这个脚本是
 header（Cache-control：private）的同一个文件夹上创建的，所以我放了$ file。 
 header（Content-type：application / force-download）; 
 header（Content-transfer-encoding：binary \\\
）; 
 header（Content-disposition：attachment; filename = \$ filename \）; 
 header（Content-Length：.filesize（$ filepath））; 
 readfile（$ filepath）; 
出口; 
  

I need some eduction please. At the end of each month, I want to download some data from my webserver to my local PC. So, I've written a little script for that, which selects the data from the DB. Next, I want to download it. I've tried this:

$file=$month . '.txt';
$handle=fopen($file, "w");
header("Content-Type: application/text");
header("Content-Disposition: attachment, filename=" . $month . '.txt');
while ($row=mysql_fetch_array($res))
    {
    $writestring = $row['data_I_want'] . "\r\n";
    fwrite($handle, $writestring);
    }
fclose($handle);

If I run this, then the file is created, but my file doesn't contain the data that I want. Instead I get a dump from the HTML-file in my browser.. What am I doing wrong.. Thanks, Xpoes

解决方案

Below script will help you download the file created

//Below is where you create particular month's text file
$file=$month . '.txt';
$handle=fopen($file, "w");
while ($row=mysql_fetch_array($res)){
    $writestring = $row['data_I_want'] . "\r\n";
    fwrite($handle, $writestring);
}
fclose($handle);
//Now the file is ready with data from database

//Add below to download the text file created
$filename = $file; //name of the file
$filepath = $file; //location of the file. I have put $file since your file is create on the same folder where this script is
header("Cache-control: private");
header("Content-type: application/force-download");
header("Content-transfer-encoding: binary\n");
header("Content-disposition: attachment; filename=\"$filename\"");
header("Content-Length: ".filesize($filepath));
readfile($filepath);
exit;
