Download the PHP package elliotjreed/ai without Composer

A library for interacting with Claude AI and ChatGPT.

At present only text requests and responses are supported.

Usage

Install via Composer:

There are two classes, one for Claude AI, and one for ChatGPT.

Each take the first argument in the constructor as your API key, and the second argument as the model you want to use.

You can optionally provide a Guzzle HTTP client:

This could be useful where you are using a framework such as Symfony, you could autowire the service and reference a configured Guzzle client.

Here's an example of a Symfony integration in the services.yaml file:

Anthropic Claude AI

For a really simple request and response:

You can provide a role too, as well as additional context, data, examples, setting the temperature (between 0 and 1, basically how "creative" you want the AI to be), and the maximum tokens to use (recommended if the user input is from a indirect source, for example an online chatbot):

If you want to keep a conversation going (like you would on ChatGPT or Claude's website or app), you can pass through the history from the previous response to a new request:

Development

Getting Started

PHP 8.2 or above and Composer is expected to be installed.

Installing Composer

For instructions on how to install Composer visit getcomposer.org.

Installing

After cloning this repository, change into the newly created directory and run:

or if you have installed Composer locally in your current directory:

This will install all dependencies needed for the project.

Henceforth, the rest of this README will assume composer is installed globally (ie. if you are using composer.phar you will need to use composer.phar instead of composer in your terminal / command-line).

Running the Tests

Unit tests

Unit testing in this project is via PHPUnit.

All unit tests can be run by executing:

Debugging

To have PHPUnit stop and report on the first failing test encountered, run:

Code formatting

A standard for code style can be important when working in teams, as it means that less time is spent by developers processing what they are reading (as everything will be consistent).

Code formatting is automated via PHP-CS-Fixer. PHP-CS-Fixer will not format line lengths which do form part of the PSR-2 coding standards so these will product warnings when checked by PHP Code Sniffer.

These can be run by executing:

Running everything

All the tests can be run by executing:

Outdated dependencies

Checking for outdated Composer dependencies can be performed by executing:

Validating Composer configuration

Checking that the composer.json is valid can be performed by executing:

Running via GNU Make

If GNU Make is installed, you can replace the above composer command prefixes with make.

All the tests can be run by executing:

Running the tests on a Continuous Integration platform (eg. Github Actions)

Specific output formats better suited to CI platforms are included as Composer scripts.

To output unit test coverage in text and Clover XML format (which can be used for services such as Coveralls):

To output PHP-CS-Fixer (dry run) and PHPCS results in checkstyle format (which GitHub Actions will use to output a readable format):

Github Actions

Look at the example in .github/workflows/php.yml.
