Requirements

Installation

composer require omaralalwi/gpdf

Publish Resources

After installation, publish the config and fonts resources by running the following commands in the root project path:

php vendor/omaralalwi/gpdf/scripts/publish_fonts.php

php vendor/omaralalwi/gpdf/scripts/publish_config.php

Note for Publish Issues: If you encounter any issues while publishing, manually copy the vendor/omaralalwi/gpdf/assets/fonts folder to public/vendor/gpdf and ensure the fonts are in public/vendor/gpdf/fonts. Also, copy vendor/omaralalwi/gpdf/config/gpdf.php to the /config folder in the root path.

Usage with Native PHP Apps

After installing the package and publishing resources, include autoload.php and use the Gpdf class.

Basic Usage

require_once __DIR__ . '/vendor/autoload.php';

use Omaralalwi\Gpdf\Gpdf;
use Omaralalwi\Gpdf\GpdfConfig;

$htmlFile = __DIR__ . '/contents/example-1.html';
$content = file_get_contents($htmlFile);
$gpdfConfigFile = require_once 'config/gpdf.php';

$config = new GpdfConfig($gpdfConfigFile);
$gpdf = new Gpdf($config);
$pdfContent = $gpdf->generate($content);

header('Content-Type: application/pdf');
echo $pdfContent;

Note: Customize the settings file as needed.

Stream Generated PDF Files

Stream a PDF directly to the browser using generateWithStream:

require_once __DIR__ . '/vendor/autoload.php';

use Omaralalwi\Gpdf\Gpdf;
use Omaralalwi\Gpdf\GpdfConfig;

$htmlFile = __DIR__ . '/contents/example-1.html';
$content = file_get_contents($htmlFile);

$gpdfConfigFile = require_once 'config/gpdf.php';
$config = new GpdfConfig($gpdfConfigFile);

$gpdf = new Gpdf($config);
$pdfContent = $gpdf->generateWithStream($content, 'demo-file-name', true);

header('Content-Type: application/pdf');
echo $pdfContent;

Store Files To Local

Save a PDF files to local storage using generateWithStore:

Note By default it store files to local driver.

<?php

require_once __DIR__ . '/vendor/autoload.php';

use Omaralalwi\Gpdf\Gpdf;
use Omaralalwi\Gpdf\GpdfConfig;
use Omaralalwi\Gpdf\Enums\{GpdfDefaultSettings, GpdfSettingKeys, GpdfDefaultSupportedFonts};

$htmlFile = __DIR__ . '/contents/example-1.html';
$content = file_get_contents($htmlFile);

$gpdfConfigFile = require_once ('config/gpdf.php');
$config = new GpdfConfig($gpdfConfigFile);

$gpdf = new Gpdf($config);
$sslVerify = false;
$file = $gpdf->generateWithStore($content,null,null, false , $sslVerify); // $sslVerify must be true in production
$fileUrl = $file['ObjectURL'];

return $fileUrl;  // get file url as string to store it in db or do any action

generateWithStore params

Parameter Type Description
html file string The HTML content to be stored.
store path or bucket name with s3 string The path where the file will be stored, with S3 store this should bucket name.
file name string The name of the file.
with stream bool If you need to stream the file to the browser after storing, set this to true.
sslVerify bool If with stream is set to true, you should set this to true in production to verify SSL.

Store Files To S3

same to store in local, just replace local path with bucket name, and replace generateWithStore with generateWithStoreToS3 .

<?php

require_once __DIR__ . '/vendor/autoload.php';

use Omaralalwi\Gpdf\Gpdf;
use Omaralalwi\Gpdf\GpdfConfig;
use Omaralalwi\Gpdf\Enums\{GpdfDefaultSettings, GpdfSettingKeys, GpdfDefaultSupportedFonts};

$htmlFile = __DIR__ . '/contents/example-1.html';
$content = file_get_contents($htmlFile);

$gpdfConfigFile = require_once ('config/gpdf.php');
$config = new GpdfConfig($gpdfConfigFile);

$gpdf = new Gpdf($config);
$fileName = "pdf-file-with-store-to-s3";
$sslVerify = true;
$file = $gpdf->generateWithStoreToS3($content,null,$fileName, true, $sslVerify);
$fileUrl = $file['ObjectURL'];

Demo Native PHP App

please see this Demo Native PHP app contain more detailed examples and cases like pass dynamic parameters for html file & pass inline configs , .. and another cases.

Usage with Laravel

Using the Gpdf Facade

use Omaralalwi\Gpdf\Facade\Gpdf as GpdfFacade;

public function generatePdf()
{
    $html = view('pdf.example-1')->render();
    $pdfContent = GpdfFacade::generate($html);
    return response($pdfContent, 200, ['Content-Type' => 'application/pdf']);
}

Using Dependency Injection

use Omaralalwi\Gpdf\Gpdf;

public function generateSecondWayPdf(Gpdf $gpdf)
{
    $html = view('pdf.example-2')->render();
    $pdfFile = $gpdf->generate($html);
    return response($pdfFile, 200, ['Content-Type' => 'application/pdf']);
}

Stream Generated PDF Files

Stream a PDF directly to the browser using generateWithStream:

// by default it store files to local driver (path should in public path).
public function generateAndStream()
{
    $html = view('pdf.example-2')->render();
    $gpdf = app(Gpdf::class);
    $gpdf->generateWithStream($html, 'test-streamed-pdf', true);
    return response(null, 200, ['Content-Type' => 'application/pdf']);
}

Storing Generated PDF Files

Store Files To local

Save a PDF to storage using generateWithStore:

Note By default it store files to local driver (ensure that: the store path is access able for read and write).

please see generateWithStore params .

public function generateAndStore()
{
    $html = view('pdf.example-2')->render();
    $gpdf = app(Gpdf::class);
    $storePath = storage_path('app/downloads/users/');
    $gpdf->generateWithStore($html, $storePath, 'test-stored-pdf-file', true, false); // ssl verify should be true in production .
    return $file['ObjectURL']; // return file url as string , to store in db or do any action
}
// may be you will face problems with stream in local, so you can disable ssl verify in local, but should enable it in production.

Store Files To S3

same to store in local, just replace local path with bucket name, and replace generateWithStore with generateWithStoreToS3 .

Note Ensure you setup s3 configs in config file.

    public function generateAndStoreToS3()
    {
        $data = $this->getDynamicParams();
        $html = view('pdf.example-2',$data)->render();
        $gpdf = app(Gpdf::class);
        $bucketName = 'your_s3_bucket_name'; // should be read abel and write able .
        $file = $gpdf->generateWithStoreToS3($html, $bucketName, 'test-store-pdf-fle', true, true); // with s36 the ssl verify will work in local or production (always secure).
        return $file['ObjectURL']; // return file url as string , to store in db or do any action
    }
