Error header in php

Question

I want to make download counter in my site with this script :

 <?php
$counter = 'apk/counter.txt'; // text file to store download count - create manually and put a 0 (zero) in it to begin the count
$download = 'http://site.my/apk/file.apk'; // the link to your download file
$number = file_get_contents($counter); // read count file
$number++; // increment count by 1
$fh = fopen($counter, 'w'); // open count file for writing
fwrite($fh, $number); // write new count to count file
fclose($fh); // close count file
header('Location: $download'); // get download
?>

But the result say

Warning: Cannot modify header information - headers already sent by (output started at /home/user/public_html/download.php:1) in /home/user/public_html/download.php on line 9

How to fix it?

@Dagon I copy and paste the script from a website, so I dont see the space berfore — Reza Fahmi, Jul 15 '16 at 23:40
there is clearly a space in the code above, the error message is clear, not much else we can do. — , Jul 15 '16 at 23:44

It means that content has already been sent to the browser, so you can't send any more headers. It could be caused by the space preceeding your opening <?php tag.

@Dagon Assuming that `download.php` is the code in the question. – Will Vousden Jul 15 '16 at 23:40
