README

The ChatGPT PHP Client is a simple PHP library that allows you to interact with the GPT-3.5 API provided by ChatGPT. This library provides an easy way to send prompts to the GPT-3.5 engine and get responses.

Installation

You can install the ChatGPT PHP Client using Composer. Run the following command in your project directory:

composer require damienpayet50320/php-chatgpt-client-api

Usage

To use the ChatGPT PHP Client, you'll need an API key from ChatGPT. Once you have the API key, you can create an instance of the ChatGPTClient class and call the completePrompt method with your desired prompt.

Here's a simple example:

<?php

require_once 'vendor/autoload.php';

use ChatGPT\ChatGPTClient;

$api_key = 'YOUR_API_KEY';
$client = new ChatGPTClient($api_key);

$prompt = 'Hello, I need assistance in writing a paragraph about climate change.';
$options = [
    'temperature' => 0.7,
    'max_tokens' => 100
];

$result = $client->completePrompt($prompt, $options);

echo $result;

Replace 'YOUR_API_KEY' with your actual ChatGPT API key.

CompletePrompt options

• temperature (float, optional): Controls the randomness of the response. Higher values (e.g., 0.8) make the output more random, while lower values (e.g., 0.2) make it more deterministic and focused.

• max_tokens (integer, optional): Specifies the maximum number of tokens in the generated response. It allows you to limit the length of the generated text.

• top_p (float, optional): Also known as nucleus sampling or "penalty for words not in nucleus." It restricts the generated output to a cumulative probability until the specified value is reached.

• frequency_penalty (float, optional): This option allows you to tune the model to avoid repeating the same phrases or words in the output.

• presence_penalty (float, optional): This option encourages the model to include or avoid certain words in the output. A higher presence penalty discourages the model from using specific words, while a lower value encourages it.

• stop (string or array of strings, optional): You can provide a list of stop sequences to control the generation and make the model stop when it encounters any of these sequences in the output.

Requirements

• PHP 8.0 or higher
• Guzzle HTTP Client 7.x
