php - Cannot modify header information - headers already sent easy solution

Hey guys I just wanted to share this solution that I found for the error: Cannot modify header information - headers already sent.

Let's say one starts out with a code that contains headers like this:

header('Content-disposition: attachment; filename="video"');
header('Content-type: video/mp4');
$video = $_POST['$video'] ;
readfile("$video");
?>

For some reason PHP doesn't like this. To see how to fix this view answer below.

To fix this type of error you can add before the in your code and add at the end of your code after ?>

Like this:

header('Content-disposition: attachment; filename="video"');
header('Content-type: video/mp4');
$video = $_POST['$video'] ;
readfile("$video");
?>

Hope this helps. This was a simple solution that I found and it works well for me and some others I know of.
