How to generate multiple copies of same PDF file in dompdf - php

Question

I am using dompdf to generate invoices, one invoice is generated but I want to generate 3 copies of same invoice pdf file which is copy1, copy2, copy3. Each copy should start on new page of the same pdf file.
$dompdf = PDF::loadView('admin.pdf.invoice', compact('data'));
$options = [];
$options['isHtml5ParserEnabled'] = true;
$options['isRemoteEnabled'] = true;
$options['isPhpEnabled'] = true;
$dompdf->setOptions($options);
$dompdf->setPaper('A4', 'portrait');
$file =LOCAL_PDF_PATH."invoice.pdf";
$dompdf->save(LOCAL_PDF_PATH."invoice.pdf");

Answer 1

Try this code
for($i=0;$i<3;$i++){
$dompdf = PDF::loadView('admin.pdf.invoice', compact('data'));
$options = [];
$options['isHtml5ParserEnabled'] = true;
$options['isRemoteEnabled'] = true;
$options['isPhpEnabled'] = true;
$dompdf->setOptions($options);
$dompdf->setPaper('A4', 'portrait');
$file =LOCAL_PDF_PATH."invoice.pdf";
$dompdf->save(LOCAL_PDF_PATH."invoice".$i.".pdf");
}

Use array chunk for that inside your view
$columns = 3; // number of columns on a page
// calculate number of rows and break the data into chunks
$num_rows = ceil(count($data) / $columns);
$data = array_chunk($data,$num_rows);
