PLAN B:

use Milon\Barcode\DNS1D;

class BarcodeController extends Controller
{
//生成条形码
public function index(Request $request){
$cc = new DNS1D();
$title = substr($request->title,0,14); //截取title长度
for( $i=0;$i<44;$i++){
// $arr = [1,5,9,13,17,21,25,29,33,37,41]; if($i%4==0|| $i$cc->getBarcodePNG($request->num, $request-&gt;type) . &#x27;&quot; alt=&quot;barcode&quot; /&gt;&lt;/div&gt;&lt;div style=&quot;width: 155px;text-align: center&quot;&gt;&#x27;.$request->fn_sku.’

’. KaTeX parse error: Expected 'EOF', got '}' at position 121: …'; }̲else{ …cc->getBarcodePNG($request->num, $request-&gt;type) . &#x27;&quot; alt=&quot;barcode&quot; /&gt;&lt;/div&gt;&lt;div style=&quot;width: 155px;text-align: center&quot;&gt;&#x27;.$request->fn_sku.’
