Create index.php file in the folder that you want to upload file from the web address.

Go to that web address that you just have made

<?php exec("wget http://domain.com/path-to-file.zip"); ?>

OR

<?php
define('BUFSIZ', 4095);
$url = 'http://raddnipoddomengolubica.agsystem.rs/wp-content/uploads/archive_210911_091658.zip';
$rfile = fopen($url, 'r');
$lfile = fopen(basename($url), 'w');
while(!feof($rfile))
fwrite($lfile, fread($rfile, BUFSIZ), BUFSIZ);
fclose($rfile);
fclose($lfile);
?>
