无法在 php laravel 下载 csv 文件
Not able to download csv file in php laravel
这是我的控制器操作,用于下载 csv 格式的文件备份。但是我无法下载该文件。我无法理解我做错了什么。
public function backup()
{
$dummy_data = array([
'Name' => 'ABC',
'Age' => '26',
'Sex' => 'Male',
],
[
'Name' => 'C S',
'Age' => '33',
'Sex' => 'Male',
],
[
'Name' => 'Rose',
'Age' => '26',
'Sex' => 'Male',
],
[
'Name' => 'Der',
'Age' => '24',
'Sex' => 'Male',
]
);
$csv = CSV::fromArray($dummy_data)->render();
return $csv
}
我正在使用这个插件来创建 csv 文件。

更新:
echo $csv; // Gives following output
HTTP/1.0 200 OK
Cache-Control: private
Content-Disposition: attachment; filename="export.csv"
Content-Type: text/csv
Date: Wed, 14 Jan 2015 12:29:04 GMT
Pragma: cache
Name,Age,Sex
ABC,26,Male
"C S",33,Male
Rose,26,Male
Der,24,Male
试试这个...
我试过它对我有用。

导入:
Excel::load('assets/uploads/mti.xlsx', function($reader) {
// Getting all results
$results = $reader->get()->toArray();
// ->all() is a wrapper for ->get() and will work the same
// $results = $reader->all();
print_r(array_filter($results));
});
导出:
Excel::create('Filename', function($excel) {
$excel->sheet('Sheetname', function($sheet) {
$sheet->fromArray(array(
array('data1', 'data2'),
array('data3', 'data4')
));
});
})->export('xls');
