php-tcpdfHow can I use TCPDF's writeHTML() function in PHP?

The writeHTML() function in TCPDF is used to render HTML code into a PDF document. It takes two parameters: the HTML code and a boolean indicating whether to use the default font or not. Here is an example of how to use it:

<?php
// Include the TCPDF library
require_once('tcpdf/tcpdf.php');

// Create a new PDF document
$pdf = new TCPDF(PDF_PAGE_ORIENTATION, PDF_UNIT, PDF_PAGE_FORMAT, true, 'UTF-8', false);

// Set document information
$pdf->SetCreator('My App');
$pdf->SetAuthor('Me');
$pdf->SetTitle('My PDF Document');

// Add a page
$pdf->AddPage();

// Render HTML code
$html = '<h1>Hello World!</h1>';
$pdf->writeHTML($html, true);

// Output the PDF
$pdf->Output('my_document.pdf', 'I');

This code will generate a PDF document with a single page containing the text Hello World!.

Code explanation

1. require_once('tcpdf/tcpdf.php');: This includes the TCPDF library in the script.
2. $pdf = new TCPDF(PDF_PAGE_ORIENTATION, PDF_UNIT, PDF_PAGE_FORMAT, true, 'UTF-8', false);: This creates a new PDF document.
3. $pdf->SetCreator('My App');: This sets the document creator.
4. $pdf->SetAuthor('Me');: This sets the document author.
5. $pdf->SetTitle('My PDF Document');: This sets the document title.
6. $pdf->AddPage();: This adds a page to the document.
7. $html = '<h1>Hello World!</h1>';: This creates a string containing the HTML code to be rendered.
8. $pdf->writeHTML($html, true);: This renders the HTML code into the PDF document.
9. $pdf->Output('my_document.pdf', 'I');: This outputs the PDF document.
