Encode text for use with Code 128 fonts such as Libre Barcode 128. The actual encoding is done by tc-lib-barcode.
Install PHP Code 128 Encoder using Composer:
composer require hbgl/php-code-128-encoder
<?php
require __DIR__ . '/../vendor/autoload.php';
use Hbgl\Barcode\Code128Encoder;
// Encode as Code 128.
$encoded = Code128Encoder::encode('ABC123456DEF');
assert ($encoded === 'ÌABCÇ,BXÈDEFqÎ');
// Only encode using Type A.
$encodedA = Code128Encoder::encode('ABC123456DEF', 'A');
assert ($encodedA === 'ËABC123456DEFLÎ');
// Only encode using Type B.
$encodedB = Code128Encoder::encode('AcC123456DeF', 'B');
assert ($encodedB === 'ÌAcC123456DeFSÎ');
// Only encode using Type C.
$encodedC = Code128Encoder::encode('123456', 'C');
assert ($encodedC === 'Í,BXLÎ');Use it together with the Libre Barcode 128 font to show a barcode on a webpage:
<?php
require __DIR__ . '/../vendor/autoload.php';
use Hbgl\Barcode\Code128Encoder;
$content = 'ABC123456DEF';
$encoded = Code128Encoder::encode($content);
?>
