仅导出单个记录标题不是数据（laravel 5.3）

问题描述

我正在尝试从DB导出单个记录。我试图写不同的方法，但失败。

I am trying to export single record from DB. I have tried to write different methods but failed. Now I try this one here, it's just downloading the headers and no data.

public function getExport($id) {
    $student = Students::find($id);
    $filename = "students.csv";
    $handle = fopen($filename, 'w+');
    fputcsv($handle, array('name', 'class', 'section'));

    foreach($student as $row) {
        fputcsv($handle, array($row['name'], $row['class'], $row['section']));
    }

    fclose($handle);

    $headers = array(
        'Content-Type' => 'text/csv',
    );

    return Response::download($filename, 'Students.csv', $headers);
}

这里只是给出了表头而不是数据。如何获得所有？

Here it just gives the table head not data below. How can I get all?

    {
        $student = Students::find($id);
        $filename = $student->name . ".csv";
        $handle = fopen($filename, 'w+');
        fputcsv($handle, array('name', 'class', 'section'));
        fputcsv($handle, array($student->name, $student->class, $student->section));

        fclose($handle);

        $headers = array(
            'Content-Type' => 'text/csv',
        );

        return \Response::download($filename, $filename, $headers);
    }
