This script was written to create a new PDF file based on a pre-existing PDF document, converting an A4 document into an A5 booklet ready for duplex printing. Page order is adjusted, and page orientation is rotated so that it prints a landscape booklet.

For mpdf 8.0

<?php
// require composer autoload
require __DIR__ . '/vendor/autoload.php';

$mpdf = new \Mpdf\Mpdf([
    'format' => 'A4-L',

    'margin_top' => 0,
    'margin_bottom' => 0,
    'margin_header' => 0,
    'margin_footer' => 0,
]);

$pw = $mpdf->w / 2;
$ph = $mpdf->h;

$mpdf->SetDisplayMode('fullpage');

$pagecount = $mpdf->SetSourceFile('A4sourcefile.pdf');

for ($i = 1; $i <= $pagecount; $i++) {
    $mpdf->AddPage();

    // add odd pages on the left side
    $tplId = $mpdf->importPage($i);
    $mpdf->useTemplate($tplId, 0, 0, $pw, $ph);

    // add even pages on the right side
