How use dompdf to generate a simple invoice pdf?

At this moment to understand the basis in composer I have decided to create a simple pdf generator with Dompdf package.

This package is awesome and simple, to create a pdf invoice solution for download or create an automatic invoice delivery system.

The idea for monetization:
A create simple auth token system with API_KEY and token to receive JSON data for generating pdf in a simple PHP hosting.
Free hosting for testing this:

Ok, the code:

Step 1:

run this, for a run this you need to install composer
composer require dompdf/dompdf
The Dompdf documentation: :
Dompdf Documentation

Step 2:

Load vendor.autoload.php package



require 'vendor/autoload.php';

Step 3:

Use the main class to create functionalities



// Cargar paquete para usar el modulo de Dompdf
use Dompdf\Dompdf;
use Dompdf\Options;

Create an instance of the class Dompdf



$dompdf = new Dompdf();

Enable remote origins (for download image)

If not enable this, the image not render in the pdf file and break the template format preset



$options = new Options();
$options->set('isRemoteEnabled', true);
$dompdf = new Dompdf($options);

Step 4:

Create an HTML template, with a text string



$htmlTemplate = '
<style>
//all styles for the custom template 
</style>

<html>
  <head>
    <htmlcontent>
    .......
</html>
';

To pass dynamic vars using this format into the string



'.$contenidoDinamico.'

For creating bucle with PHP array using the other var to generate a string with Concat operator (htmlinfo.= 'bucleGetInfo') or array method to push data

Step 5:

Load HTML with loadHtml method of the class instance previously named



$dompdf->loadHtml($content);

Step 6:

Set a size for the page with the setPaper Method



$dompdf->setPaper('A4','landscape');

Step 7:

Server compiled and fusion HTML with a PDF format to create a pdf image:



$dompdf->render();

Step 8:

Write this information of saving in temporal server memory for sending a file to the client request



$dompdf->stream($fileName);
