Dompdf is a powerful tool that transforms HTML content into PDF documents using PHP. This article will guide you through the process of setting up Dompdf and converting HTML to PDF efficiently.

Getting Started with Dompdf

Before diving into the code, ensure you meet the following requirements:

• PHP version 7.1 or higher
• DOM extension
• MBString extension
• php-font-lib
• php-svg-lib

Installation Steps

There are multiple ways to install Dompdf. Let’s explore the easiest methods.

1. Install with Composer

Using Composer is the most efficient way to install Dompdf. Just run the following command:

composer require dompdf/dompdf

Make sure to include the Composer autoload file in your PHP script:

require 'vendor/autoload.php';

2. Manual Download

If you prefer a manual installation, you can download a packaged archive of Dompdf:

• Stable releases can be found on GitHub Releases.
• Extract the content to the desired directory.

To load Dompdf, use the following code:

require_once 'dompdf/autoload.inc.php';

Using Dompdf to Convert HTML to PDF

Now that you’ve installed Dompdf, let’s convert HTML content into a PDF. Here’s an analogy to better understand the process: Think of Dompdf as a chef in a kitchen (your code) who takes raw ingredients (HTML content) and prepares a gourmet dish (PDF document).

Here’s how the process works:

use Dompdf\Dompdf;

// Instantiate and use the dompdf class
$dompdf = new Dompdf();

// Load HTML content
$dompdf->loadHtml('Hello World');

// Set paper size and orientation
$dompdf->setPaper('A4', 'landscape');

// Render the HTML as PDF
$dompdf->render();

// Output the generated PDF to the browser
$dompdf->stream();

Troubleshooting Tips

If you run into issues, here are a few troubleshooting ideas to help you out:

• Ensure all dependencies are installed. Check if your PHP version meets the requirements.
• If the PDF doesn’t render correctly, verify your HTML content for syntax errors.
• For image-related issues, ensure file paths are correct and accessible.
• Adjust the RemoteEnabled option if accessing files from a URL.
