downloaded files going to my root directory - php

Question

I am currently building a video downloading tool using PHP. The videos are downloading without any issue by selecting the path you want but I always get a copy of the video in my root directory.
I am using the following function to download the files:
function df($urlFile){
$file_name = basename("download.png");
//save the file by using base name
$fn = file_put_contents($file_name,file_get_contents($urlFile));
header("Expires: 0");
header("Last-Modified: ".gmdate("D, d M Y H:i:s")." GMT");
header("Cache-Control: no-store, no-cache, must-revalidate");
header("Cache-Control: post-check=0, pre-check=0", false);
header("Pragma: no-cache");
header("Content-type: image/jpg");
header('Content-length: '.filesize($file_name));
header('Content-disposition: attachment; filename="'.basename($file_name).'"');
readfile($file_name);
}
df($main_url); `
df($main_url);
Can you please help to avoid the files from being saved in my directory?
I only want the videos to download normally in the path the users want and not a copy in the root directory

Answer 1

This line is doing the saving:
$fn = file_put_contents($file_name,file_get_contents($urlFile));
The file_get_contents($urlFile) part is loading the file and you could simply assign it to a variable, like this:
$myContent = file_get_contents($urlFile);
then you can do what you please with this content.
