将PHP fputcsv（）生成的CSV值包装为“”

Question

因此，我的代码使用PHP的内置fputcsv函数生成CSV文件

我的代码

$delimiter = ';';
$filename = "members_" . date('Y-m-d') . ".csv";

//create a file pointer
$f = fopen('php://memory', 'w');

//set column headers
$fields = array('"FK"','"ID"', '"Name"', '"Email"', '"Phone"', '"Created"');
fputcsv($f, $fields, $delimiter, ' ');

//move back to beginning of file
fseek($f, 0);

//set headers to download file rather than displayed
header('Content-Type: text/csv');
header('Content-Disposition: attachment; filename="' . $filename . '";');

//output all remaining data on a file pointer
fpassthru($f);
// }
exit;

输出：

FK;"ID";"Name";"Email";"Phone";"Created"

但我想要

"FK";"ID";"Name";"Email";"Phone";"Created"

请帮助我
