PHP高效开发指南：掌握阿里云OCR的并发处理技巧

<?php
// 引入阿里云SDK
require_once 'aliyun-php-sdk-core/Config.php';

// 初始化$accessKeyId和$accessKeySecret为我们申请的访问密钥
$accessKeyId = '<your-access-key-id>';
$accessKeySecret = '<your-access-key-secret>';

// 创建OCR客户端对象
$client = new DefaultAcsClient(array(
  'regionId' => 'cn-shanghai',
  'accessKeyId' => $accessKeyId,
  'accessKeySecret' => $accessKeySecret
));

// 构建请求
$request = new OcrSingleInvoiceRequest();
$request->setAcceptFormat('json'); // 设置返回的数据格式
$request->setImageURL('https://example.com/image.jpg'); // 设置需要识别的图片URL

// 发送请求并获取结果
$response = $client->getAcsResponse($request);
$result = json_decode($response->getBody());

// 输出识别的结果
foreach ($result->data->items as $item) {
  echo $item->text."
";
}
