忽略包含PHP csv文件下载的标题

I am trying to download a query as a .csv on a PHP web page, which has include_once ($_SERVER['DOCUMENT_ROOT'].'header.php'); at the top. When I use the PHP header() function to download it, the .csv file contains the html code from header.php followed by the .csv data. How do I get the .csv without the html (only the query data)?

For downloading I use:

$query_file_name = "App_data.csv";
header("Content-type: text/csv");
header("Content-Disposition: attachment; filename=$query_file_name");
$query_file = fopen("php://temp", "w");

// write file
$row = $results->fetch_assoc();
fputcsv($query_file, array_keys($row));  // csv head
fputcsv($query_file, $row);  // first line
while($row = $results->fetch_assoc()) {
    fputcsv($query_file, $row);
}
fclose($query_file);

I realize I could trim the top of the file, but I do not know how to catch this before the file downloads. Optimally, I would only like to have the html from header.php not included at all.

    You need to add a condition to skip Html Code in header.php when you are calling from csv file. I hope it' will work. please refer below code.

    $fromCsv = true;
    require_once 'header.php';
    ob_start();
    $query_file_name = "App_data.csv";
    $query_file = fopen("php://output", "w");
    // write file
    $row = $results->fetch_assoc();
    fputcsv($query_file, array_keys($row));  // csv head
    fputcsv($query_file, $row);  // first line
    while($row = $results->fetch_assoc()) {
        fputcsv($query_file, $row, ",");
    }
    header('Content-type: application/csv');
    header('Content-Disposition: attachment;filename="' . $query_file_name . '.csv"');
    header('Cache-Control: max-age=0');
    header("Expires: 0");
    header('Last-Modified: ' . gmdate('D, d M Y H:i:s') . ' GMT'); // always modified
    header('Cache-Control: cache, must-revalidate'); // HTTP/1.1
    header('Pragma: public'); // HTTP/1.0
    fpassthru($query_file);
    fclose($query_file);
    exit;
    

    in header.php, all html code move to if condition

    if (!$fromCsv)
    {
      //move all html code here
    }
