我想在codeigniter框架中添加代码128自动条形码。我为此使用了 http://davidscotttufts.com/2009/03/31/how-to-create-barcodes-in-php/，但它正在生成代码 128B 格式。我也使用过 http://www.barcodephp.com/en/download 但无法在代码点火器框架中正确添加类。任何人都可以帮助我或建议我 code128 自动条形码 php 脚本.
提前致谢

您实际上可以按照 https://github.com/tecnickcom/tc-lib-barcode/blob/develop/example/index.php 中的示例进行操作
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，如果要以其他格式打印条形码：
echo $bobj->getHtmlDiv();
这些示例使用 tc-lib-barcode （https://github.com/tecnickcom/tc-lib-barcode） PHP 软件库来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。
原始代码已经从TCPDF移植和重构，并且已经在数十亿个文档中使用。
