php如何生成不同类型的条形码

php如何利用barcode生成不同类型的条形码，下面编程教程网小编给大家详细介绍一下如何实现！

1、先安装代码库

composer require codeitnowin/barcode

2、介绍一下相关代码

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;

use CodeItNow\BarcodeBundle\Utils\BarcodeGenerator;

use CodeItNow\BarcodeBundle\Utils\QrCode;

class BarCodeController extends Controller
{
  public function index()
  {
  
    echo '<p>Example - QrCode</p>';
    $qrCode = new QrCode();
    $qrCode
      ->setText('https://ipkd.cn')
      ->setSize(300)
      ->setPadding(10)
      ->setErrorCorrection('high')
      ->setForegroundColor(array('r' => 0, 'g' => 0, 'b' => 0, 'a' => 0))
      ->setBackgroundColor(array('r' => 255, 'g' => 255, 'b' => 255, 'a' => 0))
      ->setLabel('https://ipkd.cn')
      ->setLabelFontSize(16)
      ->setImageType(QrCode::IMAGE_TYPE_PNG);
    echo '<img src="data:' . $qrCode->getContentType() . ';base64,' . $qrCode->generate() . '" />';

3、base64格式的图片数据如何转成图片

$base_img = str_replace('data:image/jpg;base64,', '', $code);
$path = "E:/Bar/2022-10-130/";
$output_file = time().rand(100,999).'.jpg';
$path = $path.$output_file;
file_put_contents($path, base64_decode($base_img));
print_r($output_file);
Buy me a cup of coffee :)
