File download using php include null values

Question

I have default csv template. I need to show this template when user click on a specific button.

The code is here

    $filePath = $_SERVER['DOCUMENT_ROOT']."/content/formatted_blank.csv";
    $csvfile  = file_get_contents($filePath);
    $filename = "formatted_blank.csv";
    echo $csvfile;
    header("Content-type: application/csv");
    header("Content-Disposition: attachment; filename=\"".$filename."\"");
    die();

The code is working fine. But the output file is not matching my default template. In default template i wrote header in 1 row But download file showing in 7th row. There is white space rows coming.

if any one know about this please help me.

You can not use header functions after echo . Make the oposite
