<?php
  //新建一个图像对象
  $image = new ZBarCodeImage("./test.png");
  // 创建一个二维码识别器
  $scanner = new ZBarCodeScanner();
  //识别图像
  $barcode = $scanner->scan($image);
  //循环输出二维码信息
  if (!empty($barcode)) {
    foreach ($barcode as $code) {
      printf("Found type %s barcode with data %s\n", $code['type'], $code['data']);
    }
