What are best practices for handling image data stored in a MySQL database and displaying it in a PDF using PHP?

When handling image data stored in a MySQL database and displaying it in a PDF using PHP, it is best practice to store the image file path in the database rather than the actual image data. This helps in reducing the database size and improves performance. To display the image in a PDF, you can retrieve the file path from the database and use PHP's image processing libraries to embed the image in the PDF.

// Retrieve image file path from MySQL database
$imagePath = "path_to_image.jpg";

// Create new PDF document
$pdf = new FPDF();
$pdf->AddPage();

// Embed image in PDF
$pdf->Image($imagePath, 10, 10, 50, 50);

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