如何在PHP中下载现有文件 [英] How to download existing file in PHP

问题描述

我的服务器上有一个pdf文件。我想创建这样的链接，用户可以点击它并下载该pdf文件。我正在使用Zend框架工作与Php。

解决方案

将此代码放在php文件中，并将其称为f.e。 download.php：

 <？php 
 
 $ fullPath =路径/到/你/ file.ext; 
 
 if（$ fd = fopen（$ fullPath，r））{
 
 $ fsize = filesize（$ fullPath）; 
 $ path_parts = pathinfo（$ fullPath）; 
 $ ext = strtolower（$ path_parts [extension]）; 
 
 header（Content-type：application / pdf）; 
 header（Content-Disposition：attachment; filename = \$ path_parts [basename]。\）; 
 header（Content-length：$ fsize）; 
 header（Cache-control：private）; 
 
 while（！feof（$ fd））{
 $ buffer = fread（$ fd，2048）; 
 echo $ buffer; 
} 
} 
 
 fclose（$ fd）; 
退出; 
 
？> 
  

示例：将此类链接放入提供文件下载的文档中： / strong>

 < a href =download.php？download_file = some_file.pdf>在这里下载< / a> ;

I have a pdf file on my server. I want to create such link that, user can click on it and download that pdf file. I am using Zend frame work with Php.

解决方案

place this code inside a php file and call it f.e. "download.php":

<?php

$fullPath = "path/to/your/file.ext";

if ($fd = fopen ($fullPath, "r")) {

    $fsize = filesize($fullPath);
    $path_parts = pathinfo($fullPath);
    $ext = strtolower($path_parts["extension"]);

    header("Content-type: application/pdf");
    header("Content-Disposition: attachment; filename=\"".$path_parts["basename"]."\"");            
    header("Content-length: $fsize");
    header("Cache-control: private");

    while(!feof($fd)) {
        $buffer = fread($fd, 2048);
        echo $buffer;
    }
}

fclose ($fd);
exit;

?>

Example: place this kind of link into the document where the file download is offered:

<a href="download.php?download_file=some_file.pdf">Download here</a>
