    You'll need to write your own copy function. First check the file size through a HTTP HEAD request, for example with this solution:

    http://php.net/manual/en/function.filesize.php#92462

    Then do this to fetch the file:

    $remote = fopen('remote-file', 'r');
    $local = fopen('local-file', 'w');
    
    $read_bytes = 0;
    while(!feof($remote)) {
      $buffer = fread($remote, 2048);
      fwrite($local, $buffer);
    
      $read_bytes += 2048;
    
      //Use $filesize as calculated earlier to get the progress percentage
      $progress = min(100, 100 * $read_bytes / $filesize);
      //you'll need some way to send $progress to the browser.
      //maybe save it to a file and then let an Ajax call check it?
    }
    fclose($remote);
    fclose($local);

    You can't get a progress bar for a copy() call to my knowledge.
