fputcsv not displaying mysql table from php - php

Question

I have recently made a website and have a members table in my sql. I have an admin page that has the ability to download that with column names; however I used to use INTO OUTFILE but that is not allowed on my host. I came up with this code to download the file:
if(file_exists('downloads/members_'.date("m-d-Y").'.csv') == true) {
header("Location: /downloads/members_".date("m-d-Y").".csv");
}
$output = fopen('downloads/members_'.date("m-d-Y").'.csv', 'w+');
fputcsv($output, array('memberID','username', 'password', 'email', 'active', 'resetToken', 'resetComplete', 'support', 'supportToken' ));
$rows = mysql_query("SELECT * FROM members;");
while ($row = mysql_fetch_assoc($rows)) fputcsv($output,$row);
header("Location: /downloads/members_".date("m-d-Y").".csv");
exit;
This just outputs the column names and I have never used fputcsv before and am a tad confused on what I am doing wrong. I get the file to download but not with the table in it.
[EDIT] I just tried it with a valid sql query and it does not work. updated code above. Also There is stuff in the members table.

Try this:
if (isset($_POST['download'])) {
$result = mysql_query("SELECT * FROM members", $connection);
header('Content-Type: text/csv');
header('Content-Disposition: attachment;filename=yourcsv.csv');
header('Cache-Control: no-cache, no-store, must-revalidate');
header('Pragma: no-cache');
header('Expires: 0');
$csvoutput = fopen('php://output', 'w');
$row = getRow($result);
$headers = array_keys($row);//columns from db e.g, memberID','username',...
fputcsv($csvoutput, $headers);
fputcsv($csvoutput, $row);
while ($row = getRow($result)) {
fputcsv($csvoutput, $row);
}
fclose($csvoutput);
exit;
}
Here is your getRow() function:
function getRow($res){
return mysql_fetch_assoc($res);
}
And in your html:
<input type="submit" name="download" value="Download CSV">
Here is realtime demo with sqllite3 database. Uncomment the create database and insert statement in order to see the working demo. I have tested and it is working fine. I hope this will help you.
