You'd want something like this:

$csvName = "export.csv"
$sqlQuery = 'select * from sqlserver_table';
$sqlRresult = odbc_exec($conMsSql, $sql);

$fp = fopen(csvName , 'w');

while ($export = odbc_fetch_array($sqlRresult)) {
    if (!isset($headings))
    {
        $headings = array_keys($export);
        fputcsv($fp, $headings, ',', '"');
    }
    fputcsv($fp, $export, ',', '"');
}
fclose($fp);
