How can PHP be used to automate the process of converting and displaying PDF files on a website?

To automate the process of converting and displaying PDF files on a website using PHP, you can use a library like TCPDF or FPDF to generate PDF files dynamically. You can then use the header() function in PHP to set the Content-Type to application/pdf and output the generated PDF file directly to the browser for display.

require('fpdf.php');

$pdf = new FPDF();
$pdf->AddPage();
$pdf->SetFont('Arial','B',16);
$pdf->Cell(40,10,'Hello World!');

header('Content-Type: application/pdf');
$pdf->Output();
