How can the use of superglobal arrays like $_POST impact the functionality of passing variables to FPDF in PHP scripts?

Using superglobal arrays like $_POST can impact the functionality of passing variables to FPDF in PHP scripts because FPDF requires variables to be passed directly as arguments to its methods, rather than accessing them through superglobals. To solve this issue, you can extract the necessary variables from $_POST and pass them as arguments to FPDF methods. 

// Extract variables from $_POST
$name = $_POST['name'];
$age = $_POST['age'];

// Create FPDF object
$pdf = new FPDF();
$pdf->AddPage();
$pdf->SetFont('Arial', 'B', 16);
$pdf->Cell(40, 10, 'Name: ' . $name);
$pdf->Cell(40, 10, 'Age: ' . $age);

// Output PDF
$pdf->Output();
