我想创建一个带有新行的csv输出，以便从每组数据开始。 我得到的文件，但没有换行符 my output page

$values = mysqli_query($dbc, "SELECT specials.specials_id, specials.products_id,specials_new_products_price, products.products_image,  products.products_price,products.products_image, products.products_quantity,products.products_model,products_description.products_name,products_description.products_description
FROM specials
JOIN products_description
JOIN products
WHERE specials.products_id = products.products_id AND specials.products_id = products_description.products_id AND products.products_quantity>0");
while ($rowr = mysqli_fetch_row($values)) {
 for ($j=0;$j<$numberOfRows;$j++) {
  $csv_output .= $rowr[$j].", ";
 }
 $csv_output .= "\n";
}

}

print $csv_output;
exit;
