在PHP类中传递Foreach值

Question

如何在类中传递foreach值，下面是我的代码

$pdf->addPDF('samplepdfs/1.pdf', 'all')
    ->addPDF('samplepdfs/2.pdf', 'all')
    ->addPDF('samplepdfs/3.pdf', 'all')
    ->addPDF('samplepdfs/4.pdf', 'all')
    ->addPDF('samplepdfs/all.pdf', 'all')
    ->merge('file', 'samplepdfs/all1.pdf');

我正试图通过从形式上获取帖子来传递价值。

foreach($_POST['docs'] as $att ){
    $nAtt .= "addPDF('$path.$att', 'all')->" ;
    }


$pdf->$nAtt.merge('file', $mergeName);

但这不管用。请帮帮我。

Answer 1

在循环中添加

foreach($_POST['docs'] as $att ){
    $pdf->addPDF($path.$att, 'all');
}


$pdf->merge('file', $mergeName);
