What are some best practices for automating the merging of multiple PDF documents using TCPDF in PHP?

Merging multiple PDF documents using TCPDF in PHP can be achieved by first creating a new TCPDF instance, then adding each individual PDF document using the `addPage` method. Finally, output the merged PDF document using the `Output` method. 

require_once('tcpdf.php');

// Create new TCPDF instance
$pdf = new TCPDF();

// Add first PDF document
$pdf->setSourceFile('document1.pdf');
$tplIdx = $pdf->importPage(1);
$pdf->AddPage();
$pdf->useTemplate($tplIdx, 0, 0);

// Add second PDF document
$pdf->setSourceFile('document2.pdf');
$tplIdx = $pdf->importPage(1);
$pdf->AddPage();
$pdf->useTemplate($tplIdx, 0, 0);

// Output merged PDF document
$pdf->Output('merged_document.pdf', 'I');
