我想在codeigniter框架中添加代码128自动条形码。我使用了http://davidscotttufts.com/2009/03/31/how-to-create-barcodes-in-php/但是它生成了代码128B格式。我也使用了http://www.barcodephp.com/en/download但是无法正确添加类codeigniter framework.Can任何人可以帮助我或建议我code128自动条码PHP脚本。
提前致谢

答案 0 :(得分：0)
您实际上可以按照https://github.com/tecnickcom/tc-lib-barcode/blob/develop/example/index.php
上的示例进行操作例如：
$bobj = $barcode->getBarcodeObj('QRCODE,H', 'hello world', -4, -4, 'black');
echo "<img alt=\"Embedded Image\" src=\"data:image/png;base64,".base64_encode($bobj->getPngData())."\" />";
或者如果您想以不同的格式打印条形码：
echo $bobj->getHtmlDiv();
这些示例使用tc-lib-barcode（https://github.com/tecnickcom/tc-lib-barcode）PHP软件库生成线性和二维条形码。
源代码完全符合PSR-2标准，可以使用Composer轻松添加到PHP项目中。
原始代码已从TCPDF移植并重构，并已在数十亿份文档中使用。
