Php file download solution

PHP file downloading: the solution to corrupted PHP file content with garbled characters requires PHP file downloading.

Just copy the code and change it.

A lot of results have also come out.

After clicking download, I thought the file was downloaded. who knows that the file was damaged when the image was opened, so I observed the file size. it seems that it is about 1 KB more.

Use PS to open it. well, the system prompts that the image is damaged, but the image can be displayed.

So I think it's the extra 1kb problem.

Then, I upload a txt file and download it.

It was found that the front and back of the file contain a few more characters.

Then I was wondering how to remove it. various Baidu, Google, and questions on the forum.

Finally, after more than an hour of searching, I finally found a solution.

The code is as follows:

public function download(){    $upload=M('upload');    $data=$upload->find($_GET['id']);    if(empty($data)){        header('HTTP/1.0 404 Not Found');        header('Location: .');    }else{    $path='./public/Uploads/'.$data['savename'];    header("Content-Type:".$data['type']);    header('Content-Disposition: attachment; filename="'.$data['name'].'"');    header('Content-Length:'.$data['size']);    ob_clean();    flush();    readfile($path);    }}

Note:

ob_clean();flush();

This is the key. with these two functions, the image is opened normally and the text is not garbled.
