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();

fputcsv
implode
