excel - laravel excel 获取标题和 maatwebsite

Question

我只想获取 Excel 第一列，该列将作为列名称。

我正在使用此代码

Excel::load($request->file, function ($reader) use($request) {

$torarray=$reader->toArray();
            $line0 = $torarray[0];
            $headers = array_keys($line0);
            $excel_header=$headers;
        });

有时有效，有时无效。当不处理某些文件时，我在下面写并且可以工作

$torarray=$reader->toArray();
            $line0 = $torarray[0][0];
            $headers = array_keys($line0);
            $excel_header=$headers;
        });

我不明白什么是正确的解决方案。

谢谢@mahmoud-zalt

只是想分享我如何在 Laravel 5.5 中使用它:

$reader = Excel::load(storage_path() . '/uploads/tracking-number/' . $fileName)->get();
$headerRow = $reader->first()->keys()->toArray();

JSON:

["date","reference_no","tracking_notrace_webhttpwww.17track.com_for_eub_and_httpwww.cacesapostal.com_for_swiss_post","destination_country","receiver","tel","state","city","post_code","address","weightkg","quantity","valueusd","description","parcelquantity",0]

var_export:

array (
  0 => 'date',
  1 => 'reference_no',
  2 => 'tracking_notrace_webhttpwww.17track.com_for_eub_and_httpwww.cacesapostal.com_for_swiss_post',
  3 => 'destination_country',
  4 => 'receiver',
  5 => 'tel',
  6 => 'state',
  7 => 'city',
  8 => 'post_code',
  9 => 'address',
  10 => 'weightkg',
  11 => 'quantity',
  12 => 'valueusd',
  13 => 'description',
  14 => 'parcelquantity',
  15 => 0,
)

print_r

Array
(
    [0] => date
    [1] => reference_no
    [2] => tracking_notrace_webhttpwww.17track.com_for_eub_and_httpwww.cacesapostal.com_for_swiss_post
    [3] => destination_country
    [4] => receiver
    [5] => tel
    [6] => state
    [7] => city
    [8] => post_code
    [9] => address
    [10] => weightkg
    [11] => quantity
    [12] => valueusd
    [13] => description
    [14] => parcelquantity
    [15] => 0
)
