How to realize the business license identification function through PHP docking with Alibaba Cloud OCR interface

Overview:
In recent years, with the continuous development of the Internet, more and more companies have chosen to operate and handle online A business license has become a necessary step for establishing a business. However, manually entering business license information is a time-consuming and error-prone task. In order to improve work efficiency and reduce error rates, we can use the OCR interface provided by Alibaba Cloud to realize automatic identification of business licenses. This article will introduce how to use PHP to connect to the Alibaba Cloud OCR interface to implement the business license identification function.

Step 1: Apply for an Alibaba Cloud account and activate the OCR service

First, we need to apply for an Alibaba Cloud account (if you already have one, skip this step). Then search for "OCR" on the Alibaba Cloud console and enter the "OCR Text Recognition" service. Follow the guidance to activate the OCR service and obtain the access key AK (Access Key) and SK (Access Secret).

Step 2: Install dependent libraries

In the PHP project, we need to use the SDK officially provided by Alibaba Cloud to complete the docking with the OCR interface. Please make sure your PHP project has Composer installed, and then execute the following command to install the relevant dependent libraries:

composer require alibabacloud/sdk

Step 3: Write code to implement the business license recognition function

First, we need to create A businessLicenseOCR.php file and paste the following code into the file:

<?php
require 'vendor/autoload.php'; // 引入SDK的自动加载文件

use AlibabaCloudClientAlibabaCloud;
use AlibabaCloudClientExceptionClientException;
use AlibabaCloudClientExceptionServerException;
use AlibabaCloudOcrOcr;

// 通过AK和SK初始化阿里云客户端
AlibabaCloud::accessKeyClient('YOUR_ACCESS_KEY', 'YOUR_ACCESS_SECRET')->regionId('cn-hangzhou')->asDefaultClient();

function recognizeBusinessLicense($imagePath)
{
    try {
        $result = Ocr::v20191230()->recognizeBusinessLicense()
            ->format('json')
            ->imageURL($imagePath) // 要识别的营业执照图片路径
            ->execute();

        return $result->body;
    } catch (ClientException $e) {
        throw new Exception($e->getMessage());
    } catch (ServerException $e) {
        throw new Exception($e->getMessage());
    }
}

$imagePath = 'path/to/business_license.jpg'; // 要识别的营业执照图片路径

try {
    $result = recognizeBusinessLicense($imagePath);
    var_dump($result);
} catch (Exception $e) {
    die($e->getMessage());
}

Please note to replace YOUR_ACCESS_KEY and YOUR_ACCESS_SECRET in the code For the access key AK and key SK you obtained in step 1.

Then, you need to place the business license image to be recognized in the same directory as the businessLicenseOCR.php file, and change the 'path/to/business_license.jpg' in the code Replace with the actual image path.

Finally, run the businessLicenseOCR.php file, and you will see the recognition results of the business license in the command line interface.

Summary:
Through the above steps, we successfully used PHP to connect to the Alibaba Cloud OCR interface and realized the automatic identification function of business licenses. In this way, we can save the tedious process of manually entering business license information and improve work efficiency and accuracy. Relevant code examples can be found on GitHub.
