What are common errors when generating a PDF file in PHP?

Common errors when generating a PDF file in PHP include not setting the correct headers, not using the appropriate library or function to create the PDF, and not handling errors properly. To solve these issues, make sure to set the header content type to "application/pdf", use a reliable library like TCPDF or FPDF to create the PDF, and implement error handling to catch any potential issues during the PDF generation process. 

// Set the correct headers for PDF generation
header('Content-type: application/pdf');

// Use TCPDF library to create a PDF
require_once('tcpdf/tcpdf.php');

$pdf = new TCPDF();

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

// Output the PDF
$pdf->Output('example.pdf', 'D');
