tc-lib-barcode is a pure-PHP library that encodes data as linear, 2D and postal barcode symbols and renders them as SVG, PNG, HTML or text.

• SVG image (file, inline code, or standalone document)
• PNG image (via GD or Imagick)
• GD image object
• HTML div elements
• Character grid string
• Array of bar coordinates

Width, height, padding, foreground and background color are set per barcode.

• PHP 8.2 or later
• Extensions: gd
• Optional extensions: bcmath (speeds up the arbitrary precision arithmetic used by the IMB and PDF417 types, a pure-PHP implementation is used when it is missing)
• Composer

composer require tecnickcom/tc-lib-barcode

<?php

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

$barcode = new \Com\Tecnick\Barcode\Barcode();
$bobj = $barcode->getBarcodeObj(
    type: 'QRCODE,H',
    code: 'https://tecnick.com',
    width: -4,
    height: -4,
    color: 'black',
    padding: [-2, -2, -2, -2],
)->setBackgroundColor('white');

echo $bobj->getInlineSvgCode();
