Answer 1

This worked for me.
function downloadCSV($data)
{
$filename = date("Y-m-d").".csv";
header('Content-type: application/csv');
header('Content-Disposition: attachment; filename=' . $filename);
header("Content-Transfer-Encoding: UTF-8");
$f = fopen('php://output', 'a');
fputcsv($f, array_keys($data[0]));
foreach ($data as $row)
{
fputcsv($f, $row);
}
fclose($f);
}

Try this after opening the file, you want to write in e.g. i want to write a file at below path:
$fp = fopen('csvfiles/myfile.csv','w')
You have to enter headers separately, so for this make an array of headers like:
$csv_fields=array();
$csv_fields[] = 'Enquiry id';
$csv_fields[] = 'Date';
$csv_fields[] = 'Name';
$csv_fields[] = 'Email';
$csv_fields[] = 'Telephone';
$csv_fields[] = 'Customer Request';
$csv_fields[] = 'Special Request';
After making headers add these headers to the file.
fputcsv($fp, $csv_fields);
while($row = mysql_fetch_assoc($details)) {
fputcsv($fp,$row);
}
fclose($fp);
Also add following headers on top so that file can be viewed easily:
header("content-type: application/force-download");
header('Content-Type: application/csv');
header('Pragma: no-cache');
