Как дать новую строку в записях из базы данных в Excel

Проблема заключается в последней записи, в которой $ fetch == 29. Если я не выберу этот последний вариант на моей странице выбора, все остальные записи не появятся в следующей строке. Есть ли способ поставить \n в другое место, чтобы неважно, какие записи я выбираю, он всегда дает новую строку для каждой строки.

Здесь код:

<?php

header("Content-type: text/csv; charset=UTF-8");
header('Content-Disposition: attachment; filename=Mr Lucky - Selected Backcheck data.csv');
//connection

$dbhost = 'xxx.xxx.xxx.xxx';
$dbuser = 'xxxxx';
$dbpass = 'xxxxx';
$conn = mysql_connect($dbhost, $dbuser, $dbpass);
if (!$conn) {
    echo "Error connection";
}
//select db
$select_db = mysql_select_db('xxxxxxxxx_ssi', $conn);
if (!$select_db) {
    echo "Error to select database";
}

mysql_set_charset("utf8", $conn);

//Mysql query to get records from database
$user_query = mysql_query('SELECT details_ID, details_Interviewer, details_Name,        details_Phone, details_Address, details_City, details_Age, details_Gender, details_SEC,      details_Education, details_Occupation, details_time, details_TomMQ1, details_TomMQ4, details_L1M, details_favSalty, details_Q11Top, details_Q11Top2, details_ST1, details_ST2, details_ST3, details_ST4, details_ST5, details_Lays, details_KK, details_Bingo, details_Balaji, details_Q15, details_AdSeen FROM lucky44_data5 WHERE details_last=1');

//Code to show headings
$contents = "Password\t Interviewer code\t Name\t Phone\t Address\t City\t Age\t Gender\t SEC\t Education\t Occupation\t Time taken(mins)\t TOM MQ1(Macro)\t TOM Q4a (Salty)\t L1M Q7c\t Favorite salty Q5a\t Consideration top Box (Q11a)\t C Top 2 Box (Q11a)\t Brand I love\t Tastes better than other brands\t Have flavors you like\t Offers flavors which are different from others\t Have great advertising\t No. of statements endorsed for Lays\t No. of statements endorsed for KK\t No. of statements endorsed for Bingo\t No. of statements endorsed for Balaji\t Q15-Most Popular brand\t No. of seen ads (out of 5)\n";


//While loop to fetch the records
