PHP Barcode Generator
This is an easy to use, non-bloated, framework independent, barcode generator in PHP.
It creates SVG, PNG, JPG and HTML images, from the most used 1D barcode standards.
The codebase is based on the TCPDF barcode generator by Nicola Asuni. This code is therefor licensed under LGPLv3.
No support for...
We do not support any 2D barcodes, like QR codes. We also only generate the 'bars' part of a barcode. If you want text of the code below the barcode, you could add it later to the output of this package.
Installation
Install through composer:
composer require picqer/php-barcode-generator
If you want to generate PNG or JPG images, you need the GD library or Imagick installed on your system as well.
Usage
Initiate the barcode generator for the output you want, then call the ->getBarcode() routine as many times as you want.
<?php require 'vendor/autoload.php'; // This will output the barcode as HTML output to display in the browser $generator = new Picqer\Barcode\BarcodeGeneratorHTML(); echo $generator->getBarcode('081231723897', $generator::TYPE_CODE_128);
The getBarcode()
method accepts the following parameters:
$barcode
String needed to encode in the barcode$type
Type of barcode, use the constants defined in the class$widthFactor
Width is based on the length of the data, with this factor you can make the barcode bars wider than default$height
The total height of the barcode in pixels$foregroundColor
Hex code as string, or array of RGB, of the colors of the bars (the foreground color)
Example of usage of all parameters:
<?php require 'vendor/autoload.php'; $redColor = [255, 0, 0]; $generator = new Picqer\Barcode\BarcodeGeneratorPNG(); file_put_contents('barcode.png', $generator->getBarcode('081231723897', $generator::TYPE_CODE_128, 3, 50, $redColor));
Image types
$generatorSVG = new Picqer\Barcode\BarcodeGeneratorSVG(); // Vector based SVG $generatorPNG = new Picqer\Barcode\BarcodeGeneratorPNG(); // Pixel based PNG $generatorJPG = new Picqer\Barcode\BarcodeGeneratorJPG(); // Pixel based JPG $generatorHTML = new Picqer\Barcode\BarcodeGeneratorHTML(); // Pixel based HTML $generatorHTML = new Picqer\Barcode\BarcodeGeneratorDynamicHTML(); // Vector based HTML
Accepted barcode types
These barcode types are supported. All types support different character sets or have mandatory lengths. Please see wikipedia for supported chars and lengths per type.
Most used types are TYPE_CODE_128 and TYPE_CODE_39. Because of the best scanner support, variable length and most chars supported.

See example images for all supported barcode types
A note about PNG and JPG images
If you want to use PNG or JPG images, you need to install Imagick or the GD library. This package will use Imagick if that is installed, or fall back to GD. If you have both installed but you want a specific method, you can use $generator->useGd()
or $generator->useImagick()
to force your preference.
Examples
Embedded PNG image in HTML
$generator = new Picqer\Barcode\BarcodeGeneratorPNG(); echo '<img src="data:image/png;base64,' . base64_encode($generator->getBarcode('081231723897', $generator::TYPE_CODE_128)) . '">';
Save JPG barcode to disk
$generator = new Picqer\Barcode\BarcodeGeneratorJPG(); file_put_contents('barcode.jpg', $generator->getBarcode('081231723897', $generator::TYPE_CODABAR));
Oneliner SVG output to disk
file_put_contents('barcode.svg', (new Picqer\Barcode\BarcodeGeneratorSVG())->getBarcode('6825ME601', Picqer\Barcode\BarcodeGeneratorSVG::TYPE_KIX));
