How to use PHP and Alibaba Cloud OCR to identify the registered capital of a business license?

A business license is an integral part of the company registration process. Among them, registered capital is a very important piece of information on the business license. Identifying registered capital through traditional manual methods will consume a lot of time and energy, but with the help of modern technologies, such as PHP and Alibaba Cloud OCR, we can quickly and accurately identify the registered capital on the business license. This article will introduce how to use PHP and Alibaba Cloud OCR to achieve this goal.

First of all, we need to prepare the following working environment:

1. PHP development environment: Make sure that PHP has been installed on your server and can access the Alibaba Cloud OCR API.
2. Alibaba Cloud account: Register and log in to the Alibaba Cloud account, and create an AccessKey for OCR.
3. PHP’s HTTP request library: In this article we use the Guzzle HTTP Client library.

Next, let’s write code to identify the registered capital of the business license. First, we need to obtain the text information on the business license through Alibaba Cloud OCR API. Then, we extract the registered capital from this text information.

The following is a complete code example:

<?php
require 'vendor/autoload.php'; // 引入Guzzle库

use GuzzleHttpClient;

// 阿里云OCR的API地址
$ocrUrl = 'https://ocr.cn-shanghai.aliyuncs.com/';

// 阿里云OCR的AppKey和AppSecret
$appKey = 'YOUR_APP_KEY';
$appSecret = 'YOUR_APP_SECRET';

// 调用阿里云OCR的接口，获取营业执照的文字信息
function getBusinessLicenseInfo($imageUrl) {
    global $ocrUrl, $appKey, $appSecret;

    $client = new Client();
    $response = $client->request('POST', $ocrUrl, [
        'headers' => [
            'Authorization' => 'APPCODE ' . $appKey,
            'Content-Type' => 'application/json',
        ],
        'json' => [
            'image' => $imageUrl,
            'configure' => [
                'dataType' => 1,
            ],
        ],
    ]);

    $result = json_decode($response->getBody(), true);
    return $result;
}

// 提取营业执照上的注册资本
function extractRegisteredCapital($businessLicenseInfo) {
    $words = $businessLicenseInfo['prism_wordsInfo'];

    // 在文字信息中查找注册资本所在的行
    foreach ($words as $word) {
        if (strpos($word['word'], '注册资本') !== false) {
            // 返回注册资本的值
            return $word['word'];
        }
    }

    return null; // 如果没有找到注册资本，则返回null
}

// 测试代码
$imageUrl = 'https://example.com/business_license.jpg'; // 营业执照图片的URL地址

$businessLicenseInfo = getBusinessLicenseInfo($imageUrl);
$registeredCapital = extractRegisteredCapital($businessLicenseInfo);

echo '注册资本: ' . $registeredCapital;

?>

In the above code, you need to replace YOUR_APP_KEY and YOUR_APP_SECRET with your Alibaba Cloud OCR AppKey and AppSecret. Replace https://example.com/business_license.jpg with the URL address of the business license image you want to identify.

With the above code, we can easily use PHP and Alibaba Cloud OCR to identify the registered capital on the business license. This method not only saves a lot of time and energy, but also helps to improve the accuracy and efficiency of identification. Hope this article is helpful to you!
