php：将变量内容下载为文件 [英] php: download variable content as file

问题描述

主题是否可能？我有一个脚本执行。有一点我有一大块文本在变量中。可以将其作为可下载文件提供，而不会将可变内容写入磁盘？

 <？php 
 echo 你好; 
 //如何使此变量的内容可下载？ 
 $ download_me =下载我...; 
 echoBye; 
？> 
  

解决方案

如果您的意思是让用户点击链接，弹出一个对话框，将某些内容保存为文本文件：

 <？php 
 $ download_me =下载我...; 
 header（Content-type：text / plain）; 
 header（Content-Disposition：attachment; filename = test.txt）; 
 echo $ download_me; 
？> 
  

这是你的目标？另外，您可能想要写一些行，只允许以这种方式发送标题，如果某个 $ _ POST 或 $ _ GET 变量设置。

Is the subject possible? I have a script executing. At one point I have a large piece of text in a variable. Could I make it available as a downloadable file without actually writing variable content to disk?

<?php
    echo "Hello";
    //how do I make the content of this variable downloadable?
    $download_me = "download me...";
    echo "Bye";
?>

解决方案

If you mean letting the user click a link and have a dialog box pop up to save certain content as a text file:

<?php
$download_me = "download me...";
header("Content-type: text/plain");
header("Content-Disposition: attachment; filename=test.txt");
echo $download_me;
?>

Is that what you're aiming at? Also, you might want to write a few lines that only allows the headers to be sent this way if a certain $_POST or $_GET variable is set.
