What are some key considerations when working with templates in tcpdf and fpdi in PHP?

When working with templates in tcpdf and fpdi in PHP, it is important to ensure that the template file path is correctly specified and that the template is loaded properly before trying to use it in the PDF document. Additionally, make sure to position the template content correctly within the PDF document to avoid overlapping or misplaced content.

// Specify the path to the template file
$templatePath = 'path/to/template.pdf';

// Load the template file using FPDI
$pdf = new FPDI();
$pageCount = $pdf->setSourceFile($templatePath);

// Import the template content onto the PDF document
$templateId = $pdf->importPage(1);
$pdf->useTemplate($templateId, 0, 0, 210);

// Add additional content or modifications to the PDF document as needed
$pdf->Output('output.pdf', 'D');
