Using Dompdf: A Guide with Installation and Examples

Dompdf is a PHP library that allows you to generate PDF documents from HTML content. It is an open-source project that is maintained on GitHub by a group of developers. With Dompdf, you can easily create PDFs from HTML pages, stylesheets, and images, and it is highly customizable, so you can tailor the output to meet your specific needs.

Installing Dompdf is relatively straightforward and can be done in a few steps. First, you will need to have a web server with PHP installed. If you don’t have a server, you can download and install a local development environment such as XAMPP or WAMP. Once you have a web server, you can download the Dompdf library from the GitHub repository and extract it to your server’s document root directory.

To use Dompdf, you simply need to include the Dompdf autoloader and pass in the HTML content that you want to convert to PDF. Here is an example of how you could use Dompdf to convert a sample HTML page to PDF:


// Include the Dompdf autoloader
require_once 'dompdf/';

// Use the Dompdf namespace
use Dompdf\Dompdf;

// Create a new instance of the Dompdf class
$dompdf = new Dompdf();

// Load the HTML content
$html = file_get_contents('sample.html');

// Load the HTML into Dompdf

// Render the PDF

// Output the PDF to the browser


In this example, the HTML content is loaded from a file named “sample.html”. You can also pass in HTML content directly as a string. The render() method is used to convert the HTML content to PDF, and the stream() method is used to output the PDF to the browser.

With Dompdf, you have a powerful tool for generating PDF documents from HTML content. Whether you are creating invoices, reports, or any other type of document, Dompdf provides a fast and easy-to-use solution for converting HTML to PDF.
