在Laravel中导出数据到pdf，无论数据如何，只需下载2页

composer require dompdf/dompdf

use Dompdf\Dompdf;

public function exportToPdf()
{
    $data = []; // 获取需要导出的数据

    $html = view('pdf.template', compact('data'))->render();

    $dompdf = new Dompdf();
    $dompdf->loadHtml($html);
    $dompdf->setPaper('A4', 'portrait'); // 设置纸张大小和方向
    $dompdf->render();

    $dompdf->stream('export.pdf'); // 下载PDF文件
}

composer require barryvdh/laravel-snappy

Barryvdh\Snappy\ServiceProvider::class,

'PDF' => Barryvdh\Snappy\Facades\SnappyPdf::class,

use PDF;

public function exportToPdf()
{
    $data = []; // 获取需要导出的数据

    $pdf = PDF::loadView('pdf.template', compact('data'));
    return $pdf->download('export.pdf'); // 下载PDF文件
}
