PHP Barcode Generator
Build Status Codacy Badge

This is an easy to use, non-bloated, framework independent, barcode generator in PHP. This version has been updated to follow PSR-4 and work with PHP 7.1+.

It creates SVG, PNG, JPG and HTML images, from the most used 1D barcode standards.

The codebase is largely from the TCPDF barcode generator by Nicola Asuni. This code is therefor licensed under LGPLv3. It is still a bit of a mess, bit I will clean it in the future. I do not expect the interface of this class will change during the clean ups.

This codebase, also extending off of TCPDF barcode generator is a mostly direct copy from Picqer barcode generator. Updated to be php 7.1+ compliant.

Installation

Install through composer:

composer require brewerwall/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.

Using IMB Barcodes require bcmath extension to be installed as well.

Usage

Create a new barcode generator. This will declare the code, the type of barcode and what format the code will be rendered.

$generator = new BarcodeGenerator(BarcodeType::TYPE_CODE_128, BarcodeRender::RENDER_JPG);

// Generate our code
$generated = $generator->generate('012345678');

// Generates the same code with style updates
$generated = $generator->generate('012345678', 4, 50, '#FFCC33');

The $generator->generate() method accepts the following parameters:

  • $code Barcode value we need to generate.
  • $widthFactor (default: 2) Width is based on the length of the data, with this factor you can make the barcode bars wider than default
  • $totalHeight (default: 30) The total height of the barcode
  • $color (default: #000000) Hex code of the foreground color
