Building an Intelligent Customer Satisfaction Survey Tool with PHP and ChatGPT

Introduction

In the digital era, customer satisfaction is crucial for business growth. Customer satisfaction surveys are effective methods to measure how customers perceive products or services. Leveraging AI technology, especially the powerful natural language processing capabilities of ChatGPT, we can build an intelligent customer satisfaction survey tool to capture customer feedback more accurately and respond promptly. This article will demonstrate how to use PHP combined with the ChatGPT API to create a smart customer satisfaction system, along with practical code examples.

Environment Preparation

Before starting, please ensure you have the following:

• A server environment running PHP, such as Apache or Nginx.
• PHP version 7.0 or above.
• Composer installed to manage PHP dependencies.

Installing the ChatGPT PHP Client Library

Install OpenAI’s PHP client library via Composer by running the command:

composer require openai/api-client

This will automatically download and install the required ChatGPT PHP library.

Obtaining the OpenAI API Key

Register an account on the OpenAI website and create an API key. This key will be used for authentication in the code.

Writing PHP Code to Generate Intelligent Responses

Include the autoload file and necessary classes:

require_once 'vendor/autoload.php';

use OpenaiApiClient;
use OpenaiConfiguration;
use OpenaiModelCreateCompletionRequest;

Configure the API key:

$configuration = Configuration::getDefaultConfiguration();
$configuration->setApiKey('Authorization', 'Bearer <YOUR_API_TOKEN>');

Please replace with your actual API key.

Initialize the API client:

$apiClient = new ApiClient($configuration);

Define the function to generate intelligent replies:

function generateResponse($input) {
    global $apiClient;

    $client = new OpenaiApiChatCompletion($apiClient);

    $prompt = [
        ['role' => 'system', 'content' => 'You are a customer service representative speaking to a customer.'],
        ['role' => 'user', 'content' => $input]
    ];

    $request = new CreateCompletionRequest();
    $request->setModel('gpt-3.5-turbo');
    $request->setMessages($prompt);

    $result = $client->createCompletion($request);

    $choices = $result->getChoices();
    $response = end($choices)->getMessage()->getContent();

    return $response;
}

This function uses ChatGPT to generate intelligent replies to customer feedback, improving interaction quality.

Example Usage

Here is an example showing how to use this function:

$input = "I am very satisfied with the product quality, but hope the shipping speed can be improved.";
$response = generateResponse($input);
echo "ChatGPT's reply: " . $response;

The input is customer feedback, and the function returns an AI-generated targeted response.

Conclusion

This article introduced the complete process of building an intelligent customer satisfaction survey tool by integrating PHP with the ChatGPT API. From environment setup and dependency installation to core code implementation, it helps developers get started quickly and extend their applications. With this tool, businesses can more effectively collect customer opinions and enhance service quality and customer experience.
