What potential issues arise when trying to determine the total number of pages within a section in FPDF, especially when the number of pages is not known beforehand?

When trying to determine the total number of pages within a section in FPDF without knowing the number beforehand, potential issues can arise due to the dynamic nature of content and page breaks. One solution is to use FPDF's `getNumPages()` method after adding all content to the section to get the total number of pages. 

// Add content to the section
$pdf = new FPDF();
$pdf->AddPage();

// Add content to the section
$pdf->SetFont('Arial','B',16);
$pdf->Cell(40,10,'Hello World!');

// Get the total number of pages in the section
$totalPages = $pdf->getNumPages();

// Output the total number of pages
echo "Total number of pages in the section: " . $totalPages;
