在文件名中下载带空格的标题

Question

How do I set the right header if the filename should have a space in the name?

I tried

header( "Content-Disposition: attachment; filename=a fielename with spaces.txt");

but that gives only the suggested fielname "a" and cuts off the rest.

Answer 1

$file_name = 'a fielename with spaces.txt';
header("Content-disposition: attachment; filename=\"".$file_name."\""); 

Answer 2

header( 'Content-Disposition: attachment; filename="a fielename with spaces.txt"');
