Question

Using the following code I’m saving a .csv file on the server

foreach($list as $item)
{ 
    $csv .= join("\t", $item) . "\r\n"; 
}  

$csv = chr(255).chr(254).mb_convert_encoding($csv,"UTF-16LE","UTF-8");
header("Content-type: application/x-msdownload");
header("Content-disposition: csv; filename=CSV_".date("YmdHis").".csv; size=".strlen($csv));
$filename='CSV_'.$dateTimeNow.".csv";
file_put_contents($filename, $csv); // Create temp file

The .csv is successfully saved but the client is still receiving a download dialogue. How can I stop the download dialogue from showing?

Answer 1

If the CSV file is not intended to be sent to the client system, then you should not be setting headers that imply that you’re sending a .csv file to the client i.e. remove the header lines that causes this response to the client.
