How to Read Barcode QR Code on the Server Side Using PHP Laravel

If you want to use PHP Laravel framework to build a web barcode and QR code reader, you can implement the code logic either on the client side or on the server side. Dynamsoft provides a variety of SDKs for different platforms: desktop, mobile and web. In this article, we focus on how to leverage the PHP extension built with Dynamsoft C++ Barcode SDK to read barcode and QR code on the server side. If web client side programming is your type, please refer to https://www.dynamsoft.com/barcode-reader/sdk-javascript/.

PHP Laravel Installation on Windows and Linux

 php -r "copy('https://getcomposer.org/installer', 'composer-setup.php');" php -r "if (hash_file('sha384', 'composer-setup.php') === '55ce33d7678c5a611085589f1f3ddf8b3c52d662cd01d4ba75c0ee0459970c2200a51f492d557530c71c15d8dba01eae') < echo 'Installer verified'; >else < echo 'Installer corrupt'; unlink('composer-setup.php'); >echo PHP_EOL;" php composer-setup.php php -r "unlink('composer-setup.php');" sudo mv composer.phar /usr/local/bin/composer

Steps to Implement Server Side Barcode QR Code Reading Using PHP Laravel

In the following paragraphs, we will guide you through the process of developing a PHP Laravel project that can read barcode and QR code from image files on the server side.

Step 1: Install the PHP Barcode QR Code Reader Extension

There is no pre-built binary package. To read barcode and QR code in PHP, you need to build and install the PHP extension from source code on Windows and Linux.

Step 2: Scaffold a Laravel Project

Once the extension is installed, you can start a new Laravel project.

composer create-project laravel/laravel web-barcode-qrcode-reader 

The above command installs the latest stable version of Laravel. To avoid the compatibility issue, a better way is to specify the Laravel version number.

php artisan --version Laravel Framework 8.83.23 composer create-project laravel/laravel:^8.0 web-barcode-qrcode-reader 

Step 3: Create a Controller

Laravel controllers handle HTTP requests. We can create a controller to handle the uploaded image files and return the barcode and QR code decoding results.

php artisan make:controller ImageUploadController 

The command generates an ImageUploadController.php file in the app/Http/Controllers directory. Open the file to add the following code:

 namespace App\Http\Controllers; use Illuminate\Http\Request; use Validator; class ImageUploadController extends Controller  function __construct()  DBRInitLicense("DLS2eyJoYW5kc2hha2VDb2RlIjoiMjAwMDAxLTE2NDk4Mjk3OTI2MzUiLCJvcmdhbml6YXRpb25JRCI6IjIwMDAwMSIsInNlc3Npb25QYXNzd29yZCI6IndTcGR6Vm05WDJrcEQ5YUoifQ= p">); DBRInitRuntimeSettingsWithString("\"ImageParameter\":<\"Name\":\"BestCoverage\",\"DeblurLevel\":9,\"ExpectedBarcodesCount\":512,\"ScaleDownThreshold\":100000,\"LocalizationModes\":[<\"Mode\":\"LM_CONNECTED_BLOCKS\">,,,,],\"GrayscaleTransformationModes\":[,]>>"); > function page()  return view('barcode_qr_reader'); > function upload(Request $request)  $validation = Validator::make($request->all(), [ 'BarcodeQrImage' => 'required' ]); if($validation->passes())  $image = $request->file('BarcodeQrImage'); $image->move(public_path('images'), $image->getClientOriginalName()); $resultArray = DecodeBarcodeFile(public_path('images/' . $image->getClientOriginalName()), 0x3FF | 0x2000000 | 0x4000000 | 0x8000000 | 0x10000000); // 1D, PDF417, QRCODE, DataMatrix, Aztec Code if (is_array($resultArray))  $resultCount = count($resultArray); echo "Total count: $resultCount", "\n"; if ($resultCount > 0)  for ($i = 0; $i  $resultCount; $i++)  $result = $resultArray[$i]; echo "Barcode format: $result[0], "; echo "value: $result[1], "; echo "raw: ", bin2hex($result[2]), "\n"; echo "Localization : ", $result[3], "\n"; > > else  echo 'No barcode found.', "\n"; > > return response()->json([ 'message' => 'Successfully uploaded the image.' ]); > else  return response()->json([ 'message' => $validation->errors()->all() ]); > > > 

In __construct() method, you initialize the barcode SDK instance by setting a valid license key, which can be obtained from Dynamsoft customer portal. Calling DBRInitRuntimeSettingsWithString() is optional, because the default settings are suitable for most cases.

The uploaded images are saved to the public/images directory. The DecodeBarcodeFile() method is used to read barcode and QR code from the image file.

The next step is to create the barcode_qr_reader view.

Step 4: Create a Web View

Create a barcode_qr_reader.blade.php file in the public/resources/views directory. The file contains the HTML5 code for uploading an image via a form.

    PHP Laravel Barcode QR Reader  name="_token" content="" />   PHP Laravel Barcode QR Reader  action="" method="post" enctype="multipart/form-data"> @csrf Select barcode image:  type="file" name="BarcodeQrImage" id="BarcodeQrImage" accept="image/*">  type="submit" value="Read Barcode" name="submit">   id="image" /> var input = document.querySelector('input[type=file]'); input.onchange = function()  var file = input.files[0]; var fileReader = new FileReader(); fileReader.onload = function(e)   let image = document.getElementById('image'); image.src = e.target.result; > > fileReader.readAsDataURL(file); >    

CSRF Protection is required for the form. A convenient way is to use the @csrf Blade directive to generate the hidden token input field:

 action="" method="post" enctype="multipart/form-data"> @csrf . 

As the web page is done, one more step is to add the web routes in public/routes/web.php .

Route::get('/barcode_qr_reader', 'App\Http\Controllers\ImageUploadController@page'); Route::post('/barcode_qr_reader/upload', 'App\Http\Controllers\ImageUploadController@upload')->name('image.upload'); 

Step 5: Run the PHP Laravel Barcode QR Code Reader

Now you can run the PHP Laravel project and visit http://127.0.0.1:8000/barcode_qr_reader in your browser.

Read Barcode with a Particular Symbology using PHP Barcode Reader#

Barcode Recognition is the process of identifying the type of barcode we want to scan or read. In the previous example, we simply read a barcode without knowing its symbology type. However, in some cases, we know about the symbology of the barcode in advance. In such a scenario, we can speed up the scanning process by providing the barcode symbology explicitly to the barcode reader.

The following code sample shows how to read a barcode of a specific symbology using PHP.

Advanced Features of PHP Barcode Generator and Reader API#

Aspose.BarCode for PHP via Java provides a wide range of features for manipulating barcodes using PHP. You may have a look at the following documentation articles and simply port the Java code to PHP.
