$heading = array('Name', 'Group'); 
fputcsv($temp, $heading); 
foreach($student as $row) { 
    fputcsv($temp, array($row['name'],$row['group'])); 
    } 
    fseek($temp, 0); 
     echo fread($temp, 1024); 
     header('Content-Type: text/csv; charset=utf-8'); 
     header('Content-Disposition: attachment; filename=Student.csv');

Answer 1

每次通過數組覆蓋$values。

$values = []; 
foreach($student as $row) { 
    $values[] = array($row['name'],$row['group']); 
}
