How can PHP developers handle the output of PDF files directly without the need for intermediate HTML pages when using PDF generation libraries?

PHP developers can handle the output of PDF files directly by using PDF generation libraries like TCPDF or FPDF. These libraries allow developers to create PDF files programmatically without the need for intermediate HTML pages. By generating PDF files directly in PHP, developers can streamline the process and have more control over the content and formatting of the PDF.

// Example using TCPDF library to generate a PDF file directly
require_once('tcpdf/tcpdf.php');

$pdf = new TCPDF();
$pdf->AddPage();
$pdf->SetFont('Arial', 'B', 16);
$pdf->Cell(40, 10, 'Hello World!');
$pdf->Output('example.pdf', 'D');
