$users = array(
array("Username","Department" ,"Professional title");
array("user1","1","Secretariat","Secretary");

array("user3","3","Logistics Department","Department Member");
);
$handle = fopen("html/csvfile.csv","w");
foreach($users as $ line){
fputcsv($user,$line);
}
//When you "invite" the file, remember to "send it back"
