CodeIgniter-force_download（）无输出 [英] CodeIgniter - force_download() no output

问题描述

快速解释一下，但我无法使其工作：

Fast to explain, but I can't get it to work:

在此简单代码中，force_download函数根本不会产生任何输出。

In this simple code, the function force_download simply doesn't make any output.

$this->load->helper('download');
$data = file_get_contents("modulos/".$filename); // Read the file's contents
force_download($filename, $data);
echo $data."/".$filename;

在这里，我只是得到一个白色的屏幕，但是文件内容显示了（很奇怪，编码的内容:)
我认为这很简单，我只希望下载的文件没有其他效果，我做错了吗？

Here I just get a white screen, but the file content is show (well you know, the strange codified content :) I think it is simple enough, I just want the file downloaded with no other effect, am I doing something wrong?

推荐答案

这将与您一起使用

$this->load->helper('download');
$path = file_get_contents(base_url()."modulos/".$filename); // get file name
$name = "sample_file.pdf"; // new name for your file
force_download($name, $path); // start download`
