}
else{
$staff_list=$_FILES['file']['tmp_name'];
$handle=fopen($staff_list,"r");
// read the first line and ignore it
fgets($handle);
//count number of lines of uploaded csv file
$fh = fopen($staff_list,'rb') or die("ERROR OPENING DATA");

$file = Reader::createFromPath('path-to-your-file');
$result = $file->fetchAll();
foreach($result as $data){
// do database add here
}
