function array2csv(array &$array){
if (count($array) == 0) {
return null;
}
ob_start();
$df = fopen("php://output", 'w');
fputcsv($df, array_keys(reset($array)));
foreach ($array as $row) {
fputcsv($df, $row);
}
fclose($df);
return ob_get_clean();}function download_send_headers($filename) {
// disable caching
$now = gmdate("D, d M Y H:i:s");
header("Expires: Tue, 03 Jul 2001 06:00:00 GMT");
header("Cache-Control: max-age=0, no-cache, must-revalidate, proxy-revalidate");
header("Last-Modified: {$now} GMT");
// force download
header("Content-Type: application/force-download");
header("Content-Type: application/octet-stream");
header("Content-Type: application/download");
// disposition / encoding on response body
header("Content-Disposition: attachment;filename={$filename}");
header("Content-Transfer-Encoding: binary");}download_send_headers("data_export_" . date("Y-m-d") . ".csv");echo array2csv($array);die();
