What are some potential challenges when converting HTML code to PDF using FPDF and CKeditor?

One potential challenge when converting HTML code to PDF using FPDF and CKeditor is that certain HTML elements or styles may not be fully supported by FPDF, leading to formatting issues or missing content in the generated PDF. To address this, you can use a library like HTML2FPDF to better handle the conversion process and ensure a more accurate representation of the HTML content in the PDF.

// Include the HTML2FPDF library
require('html2fpdf.php');

// Create a new instance of HTML2FPDF
$pdf = new HTML2FPDF();

// Set the HTML content from CKeditor
$html = '<p>This is a sample HTML content from CKeditor</p>';

// Convert the HTML content to PDF
$pdf->AddPage();
$pdf->WriteHTML($html);
$pdf->Output('output.pdf', 'D');
