What are the potential challenges when handling PDF files in a database in PHP?

Potential challenges when handling PDF files in a database in PHP include ensuring proper file upload and storage, extracting text or data from the PDF, and displaying or downloading the PDF file for users. To solve these challenges, you can use libraries like TCPDF or FPDF for creating PDFs, and libraries like pdftotext or pdfparser for extracting text or data from PDFs. 

// Example code using TCPDF to create a PDF file
require_once('tcpdf/tcpdf.php');

$pdf = new TCPDF();
$pdf->AddPage();
$pdf->SetFont('Arial', 'B', 16);
$pdf->Cell(0, 10, 'Hello World', 0, 1, 'C');
$pdf->Output('example.pdf', 'F');
