Laravel：将搜索到的数据导出到excel

Question

我想把搜索到的数据导出到laravel下面是我的控制器

公共函数getUsageData(请求$request) {

    $start_date = $request->get('start_date');
    $end_date = $request->get('end_date');

    $particulars = DB::table('particulars')
        ->join('reqs', 'particulars.particular_id', "=", 'reqs.particular_id')
        ->whereBetween('date_applied', [$start_date, $end_date])
        ->select('particulars.item_name', 'particulars.unit', 'particulars.price', 'reqs.quantity_issued',
            DB::raw('particulars.price*reqs.quantity_issued AS total_cost'))
        ->get();
    if ($particulars->isEmpty()) {


        return "No Records Found...................... ";

    } else {

        $pdf = PDF::loadView('issuer.getUsageReport', ['particulars' => $particulars]);
        return $pdf->stream('getUsageReport.issuer');
    }
}

我想将这些数据检索到 excel 而不是 pdf 请帮助

Answer 1

将else { ... } 语句中的两个PDF 行替换为：

$list = $particulars->toArray();

//This line adds headers if present in your data
array_unshift($list, array_keys($list[0]));

$callback = function() use ($list) {
    $FH = fopen('php://output', 'w');
    foreach ($list as $row) { 
        fputcsv($FH, $row);
    }
    fclose($FH);
};

return response()->streamDownload($callback,"filename.csv");

根据particulars 的结构，您可能需要先对数据进行一些操作，例如变平。如果有，请在下方评论。
