Laravel: attach multiple PDFs to email - laravel

Question

Following is a code to send a PDF with email:
$pdf = PDF::loadHTML($str_html)->setPaper('a4', 'portrait');
Mail::send('emails.mail', $data, function($message) use ($data,$pdf){
$message->from('noreply#...');
$message->to('...');
$message->subject('test test');
//Attach PDF doc
$message->attachData($pdf->output(),'invoice.pdf');
});
But my requirement is to send multiple PDFs with email, how can I do this?

Answer 1

$attachments = [
// first attachment
'/path/to/file1',
// second attachment
'/path/to/file2',
...
];
$pdf = PDF::loadHTML($str_html)->setPaper('a4', 'portrait');
Mail::send('emails.mail', $data, function($message) use ($data,$pdf){
$message->from('noreply#...');
$message->to('...');
$message->subject('test test');
//Attach PDF doc
foreach($attachments as $filePath){
$message->attach($filePath);
}
});

Answer 2

taibur rahman provides an answer in comment, new PDFs variables must be added in "use", then code will be correct.
Complete Code:
$pdf = PDF::loadHTML($str_html)->setPaper('a4', 'portrait');
$pdf2 = PDF::loadHTML($str_html2)->setPaper('a4', 'portrait');
Mail::send('emails.mail', $data, function($message) use ($data, $pdf, $pdf2){
$message->from('...#...');
$message->to(...#...);
$message->subject('test test');
$message->attachData($pdf->output(),'test.pdf');
$message->attachData($pdf2->output(),'test2.pdf');
});
