To be able to generate barcode, I’ve used an existing Barcode class in Github.
I have downloaded the files in the Repo and are included in the downloadable of this tutorial, but if you want, you can download the class yourself.
1. Install a composer. If you have not installed composer yet, you may download it using this link.
2. Once the composer is installed, create your directory, in my case barcode_php.
3. Navigate to your created directory in command prompt and type in:
composer require picqer/php-barcode-generator
It would help if you had a folder vendor that contains all the necessary files to generate barcode.
Generating a Barcode
Next, we are going to generate our barcode, as you can see in the Github repo, you can use different barcode types.
As an example, please create a new file, name it as index.php and paste the codes below.
<?php require 'vendor/autoload.php'; $generator = new PicqerBarcodeBarcodeGeneratorPNG(); echo '<img src="data:image/png;base64,' . base64_encode($generator->getBarcode('081231723897', $generator::TYPE_CODE_128)) . '">'; ?>
In here we have used TYPE_CODE_128 as our barcode type and ‘081231723897’ is the text that our barcode is created from.
That ends this tutorial. Happy Coding!
