How to use PHP and Alibaba Cloud OCR to identify the company name in the business license?

Business license is a very important license in commercial activities, and the company name is a very core piece of information in the license. Due to the various formats of business licenses, manual reading of company names is very time-consuming and error-prone, so using OCR (optical character recognition) technology to automatically identify company names is a very efficient and accurate method.

Alibaba Cloud OCR is a very powerful OCR technology service that provides multiple functions, including the identification of various documents such as ID cards, bank cards, and business licenses. This article will use PHP as an example to introduce how to use Alibaba Cloud OCR to identify the company name in the business license.

First, we need to register and activate the OCR service on Alibaba Cloud. Then, create an Access Key in the Alibaba Cloud console, which will be used to access the OCR interface.

PHP provides the cURL library for HTTP requests. We can use cURL to send HTTP POST requests to the Alibaba Cloud OCR interface. The following is a simple sample code:

<?php
// 定义请求的URL和参数
$url = "https://ocrapi-advanced.taobao.com/ocrservice/businessLicense";
$data = array(
  'image' => base64_encode(file_get_contents('path/to/your/business_license.jpg')),
);

// 构建HTTP请求的Header
$header = array(
  'Authorization:APPCODE your_appcode',
  'Content-Type:application/x-www-form-urlencoded; charset=UTF-8',
);

// 创建一个cURL请求
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_HTTPHEADER, $header);
curl_setopt($ch, CURLOPT_POSTFIELDS, http_build_query($data));

// 发送请求并获取响应
$response = curl_exec($ch);
curl_close($ch);

// 解析响应数据
$result = json_decode($response, true);

// 输出公司名称
if ($result && isset($result['data']['businessLicenseName'])) {
  echo "公司名称：" . $result['data']['businessLicenseName'];
} else {
  echo "无法识别公司名称";
}
?>

In the above code, we first define the requested URL and parameters. Among them, the URL is the address of the Alibaba Cloud OCR interface, and the parameter is a Base64 encoded string containing the business license image. Read the image data of the business license through the file_get_contents function, and convert it into a Base64 encoded string using the base64_encode function.

Next, we build an HTTP request header array that contains Authorization and Content-Type header information. You need to replace your_appcode with the AppCode you obtained in the Alibaba Cloud console.

Then, we use the curl_init function to create a cURL request and set the request URL, POST method, method of returning results, request header information and request parameters. Then, use the curl_exec function to send the request and get the response result. Finally, use the curl_close function to close the cURL request.

Next, we parse the response result and convert it into a PHP array. If the recognition is successful and the response result contains the businessLicenseName field, we will output the company name. Otherwise, if it fails or the company name cannot be recognized, the corresponding prompt message will be output.

The above are the basic steps and sample code for using PHP and Alibaba Cloud OCR to identify the company name in the business license. By using OCR technology, we can automatically read the company name in the business license quickly and accurately, thereby improving work efficiency and reducing errors.
