Building an AI-powered Virtual Assistant with ChatGPT PHP in a Custom WordPress Plugin
Posted on 17th June 2023
In this tutorial, we’ll show you how to build an AI-powered virtual assistant using the open source ChatGPT PHP library and integrate it into a custom WordPress plugin.
What is ChatGPT PHP?
ChatGPT PHP is an open source library that allows you to easily build chatbots and natural language processing (NLP) applications. It provides a simple, yet powerful, API that can be used to build chatbots and NLP applications of any size and complexity.
How to Install ChatGPT PHP
ChatGPT PHP can be installed using Composer:
composer require chatgpt/php
Or you can download the latest release from GitHub:
https://github.com/chatgpt/php/releases
How to Use ChatGPT PHP
Once you have installed ChatGPT PHP, you can use it to build chatbots and NLP applications. The following is a simple example of how to use ChatGPT PHP to build a chatbot:
$bot = new ChatGPTBot();
$bot->onMessage(function($message) {
echo "You said: ".$message;
});
$bot->run();
In this example, we created a new chatbot instance and registered a message event handler. The message event handler simply echoes the message that was sent to the chatbot.
We then called the run method to start the chatbot.
How to Integrate ChatGPT PHP into a Custom WordPress Plugin
In this section, we’ll show you how to integrate ChatGPT PHP into a custom WordPress plugin.
The first thing you need to do is create a new WordPress plugin. You can do this by creating a new directory in the wp-content/plugins directory and creating a plugin.php file in that directory with the following content:
<?php
/*
Plugin Name: My Plugin
Plugin URI: https://example.com/my-plugin
Description: This is my plugin.
Version: 1.0
Author: John Doe
Author URI: https://example.com
License: GPLv2 or later
*/
// Your code goes here...
Next, you need to include the Composer autoloader in your plugin:
require_once __DIR__ . '/vendor/autoload.php';
Now you can use the ChatGPT PHP library in your plugin.

Most of us are familiar with virtual assistants like Siri, Alexa, and Google Assistant. These tools are powered by artificial intelligence (AI) and natural language processing (NLP). In this article, we’ll show you how to build a virtual assistant with ChatGPT PHP in a custom WordPress plugin.
ChatGPT is a PHP library for building chatbots. It provides an easy-to-use interface for creating, training, and deploying chatbots. ChatGPT is open source and available on GitHub.
To get started, we’ll need to create a new WordPress plugin. We’ll call our plugin “MyAssistant”.
In the plugin’s directory, create a file named “myassistant.php” and add the following code:
<?php
/*
Plugin Name: MyAssistant
Plugin URI: https://example.com/myassistant
Description: A virtual assistant powered by ChatGPT
Version: 1.0
Author: John Doe
Author URI: https://example.com
License: GPLv2 or later
*/
We'll also need to create a "config.php" file in the plugin's directory. This file will contain our ChatGPT configuration. Add the following code to "config.php":
‘chatgpt/default’,
/*
* The ChatGPT language.
*/
‘language’ => ‘en’,
/*
* The ChatGPT voice.
*/
‘voice’ => ‘en-US-Wavenet-D’,
/*
* The ChatGPT response type.
*/
‘response_type’ => ‘text’,
/*
* The ChatGPT response_format.
*/
‘response_format’ => ‘json’,
/*
* The ChatGPT response_encoding.
*/
‘response_encoding’ => ‘UTF-8’,
/*
* The ChatGPT conversation_id.
*/
‘conversation_id’ => ‘my-conversation-id’,
/*
* The ChatGPT conversation_token.
*/
‘conversation_token’ => ‘my-conversation-token’,
/*
* The ChatGPT client_id.
*/
‘client_id’ => ‘my-client-id’,
/*
* The ChatGPT client_secret.
*/
‘client_secret’ => ‘my-client-secret’,
/*
* The ChatGPT project_id.
*/
‘project_id’ => ‘my-project-id’,
/*
* The ChatGPT model_id.
*/
‘model_id’ => ‘my-model-id’,
/*
* The ChatGPT subscription_key.
*/
‘subscription_key’ => ‘my-subscription-key’,
/*
* The ChatGPT endpoint.
*/
‘endpoint’ => ‘https://api.chatgpt.com’,
];
In the “myassistant.php” file, we’ll need to require the “config.php” file and the ChatGPT library. Add the following code to the top of the “myassistant.php” file:
getResponse(‘Hi’);
echo $response;
We can also use the “getConversation” method to get the entire conversation history. Add the following code to the “myassistant.php” file:
$conversation = $chatgpt->getConversation();
echo $conversation;
We can also use the “getConfig” method to get the current configuration. Add the following code to the “myassistant.php” file:
$config = $chatgpt->getConfig();
echo $config;
We can also use the “setConfig” method to update the configuration. Add the following code to the “myassistant.php” file:
$chatgpt->setConfig(
[
‘model’ => ‘chatgpt/default’,
‘language’ => ‘en’,
‘voice’ => ‘en-US-Wavenet-D’,
‘response_type’ => ‘text’,
‘response_format’ => ‘json’,
‘response_encoding’ => ‘UTF-8’,
‘conversation_id’ => ‘my-conversation-id’,
‘conversation_token’ => ‘my-conversation-token’,
‘client_id’ => ‘my-client-id’,
‘client_secret’ => ‘my-client-secret’,
‘project_id’ => ‘my-project-id’,
‘model_id’ => ‘my-model-id’,
‘subscription_key’ => ‘my-subscription-key’,
‘endpoint’ => ‘https://api.chatgpt.com’,
]
);
We can also use the “train” method to train our chatbot. Add the following code to the “myassistant.php” file:
$chatgpt->train(
[
[
‘input’ => ‘Hi’,
‘output’ => ‘Hello!’
],
[
‘input’ => ‘How are you?’,
‘output’ => ‘I’m good, thank you for asking.’
],
[
‘input’ => ‘What’s your name?’,
‘output’ => ‘My name is John.’
],
]
);
We can also use the “evaluate” method to evaluate our chatbot. Add the following code to the “myassistant.php” file:
$metrics = $chatgpt->evaluate(
[
[
‘input’ => ‘Hi’,
‘output’ => ‘Hello!’
],
[
‘input’ => ‘How are you?’,
‘output’ => ‘I’m good, thank you for asking.’
],
[
‘input’ => ‘What’s your name?’,
‘output’ => ‘My name is John.’
],
]
);
echo $metrics;
We can also use the “log” method to log messages. Add the following code to the “myassistant.php” file:
$chatgpt->log(‘This is a log message.’);
We can also use the “debug” method to debug our chatbot. Add the following code to the “myassistant.php” file:
$chatgpt->debug(‘This is a debug message.’);
We can also use the “error” method to log error messages. Add the following code to the “myassistant.php” file:
$chatgpt->error(‘This is an error message.’);
We can also use the “warn” method to log warning messages. Add the following code to the “myassistant.php” file:
$chatgpt->warn(‘This is a warning message.’);
We can also use the “info” method to log informational messages. Add the following code to the “myassistant.php” file:
$chatgpt->info(‘This is an informational message.’);
We can also use the “setLogger” method to
