Briefly explain how PHP connects to Baidu image review interface

PHP is a server-side scripting language widely used in web development, and the Baidu image review interface is a service that can review image content. This article will introduce in detail how to use PHP to connect to Baidu image review interface and provide corresponding code examples.

First, we need to register a Baidu Cloud account and create an application. After creating the application, we will obtain an API Key and Secret Key, which are the necessary credentials to connect to Baidu's image review interface.

Next, we start writing code. First, we need to create a PHP file, such as "image_audit.php", and introduce the library file of Baidu AI SDK into this file.

<?php
  require_once 'AipImageCensor.php';

  // 设置APPID/AK/SK
  const APP_ID = 'YOUR_APP_ID';
  const API_KEY = 'YOUR_API_KEY';
  const SECRET_KEY = 'YOUR_SECRET_KEY';

  // 初始化AipImageCensor类
  $client = new AipImageCensor(APP_ID, API_KEY, SECRET_KEY);

  // 需要审核的图片路径
  $image = 'image.jpg';

  // 调用百度图像审核接口
  $result = $client->imageCensorUserDefined(file_get_contents($image));

  // 输出审核结果
  echo json_encode($result);
?>

Please replace "YOUR_APP_ID", "YOUR_API_KEY" and "YOUR_SECRET_KEY" in the code with the actual values ​​you applied for.

In the code, we first introduce the "AipImageCensor.php" file provided by Baidu AI SDK, and then set the APPID, API Key and Secret Key. Next, we create an AipImageCensor object and assign the image path to be reviewed to the variable "$image".

Finally, we call the Baidu image audit interface by calling the "imageCensorUserDefined" method of the AipImageCensor object. This method accepts a string containing the image content as a parameter and returns an audit result in JSON format.

For the convenience of demonstration, we use the "json_encode" method to simply process the audit results and output them directly to the browser. In practical applications, you can process the audit results accordingly according to specific needs.

Next, we can audit the image by accessing the "image_audit.php" file. Assume that we have named the image to be audited "image.jpg" and placed it in the same directory as the "image_audit.php" file. Enter "http://your_domain.com/image_audit.php" in your browser to see the audit results.

The above is a simple explanation and code example of using PHP to connect to Baidu's image review interface. Through the introduction of this article, you can learn how to use PHP to call the Baidu image review interface and process the review results. Hope this article can help you!
