PDF is used to read the information in a document form. The PDF file is denoted by .pdf file extension and means as Portable Document Format. A PDF document manifests information for eBooks, application forms, user manuals, other documents.

Suppose you are a Codeigniter developer and want to know how to create a PDF file from the HTML view template using the domPDF library in Codeigniter 4. In that case, this tutorial is good to go for you.

Step 1: Install Codeigniter 4

This is optional; however, if you have not created the codeigniter app, then you maygo ahead and execute the below command:

composer create-project codeigniter4/appstarter ci-news
Step 2: Install & Configure DomPDF

In this step we will require install DomPDF plugin using Composer package. Run the below command to install Composer plugin.

composer require dompdf/dompdf

Once we are done installing the PDF package in Codeigniter application. Then, go to app/Config/Autoload.php file and search for $psr4 array, here you have to register the dompdf service.

public $psr4 = [
    APP_NAMESPACE => APPPATH, // For custom app namespace
    'Config'      => APPPATH . 'Config',
    'Dompdf'      => APPPATH . 'ThirdParty/dompdf/src',
];
Step 3: Create PDF Controller

In this third step,you will create to pdfController in app/Controllers folder.

app/Controllers/PdfController.php 
loadHtml(view('pdf_view'));
        $dompdf->setPaper('A4', 'landscape');
        $dompdf->render();
        $dompdf->stream();
    }

}
Step 4: Define Route

We have to engender a route that renders the table into the view, place the following code in app/Config/Routes.php file.

app/Config/Routes.php 
$routes->get('/', 'PdfController::index');
Step 5: Create View

we have to create a pdf_view.php file that we will use to convert HTML to PDF. Place the following code inside the application/views/pdf_view.php file.

<!doctype html>
<html lang="en">

<head>
  <meta charset="utf-8">
  <meta name="viewport" content="width=device-width, initial-scale=1, shrink-to-fit=no">
