README

This PHP library provides a simple wrapper for the PerplexityAI API, allowing you to easily integrate the PerplexityAI API into your PHP projects.

Features

Easy integration with PerplexityAI API
Supports all PerplexityAI API endpoints
Utilizes PSR-17 and PSR-18 compliant HTTP clients, and factories for making API requests

Requirements

PHP 7.4 or higher
A PSR-17 HTTP Factory implementation (e.g., guzzle/psr7 or nyholm/psr7)
A PSR-18 HTTP Client implementation (e.g., guzzlehttp/guzzle or symfony/http-client)

Installation

You can install the library via Composer:

composer require softcreatr/php-perplexity-ai-sdk

Usage

First, include the library in your project:

<?php

require_once 'vendor/autoload.php';

Then, create an instance of the PerplexityAI class with your API key, organization (optional), an HTTP client, an HTTP request factory, and an HTTP stream factory:

use SoftCreatR\PerplexityAI\PerplexityAI;

$apiKey = 'your_api_key';

// Replace these lines with your chosen PSR-17 and PSR-18 compatible HTTP client and factories
$httpClient = new YourChosenHttpClient();
$requestFactory = new YourChosenRequestFactory();
$streamFactory = new YourChosenStreamFactory();
$uriFactory = new YourChosenUriFactory();

$pplx = new PerplexityAI($requestFactory, $streamFactory, $uriFactory, $httpClient, $apiKey);

Now you can call any supported PerplexityAI API endpoint using the magic method __call:

$response = $pplx->createChatCompletion([
    'model' => 'mistral-7b-instruct',
    'messages' => [
        [
            'role' => 'system',
            'content' => 'Be precise and concise.'
        ],
        [
            'role' => 'user',
            'content' => 'How many stars are there in our galaxy?'
        ]
    ],
]);

// Process the API response
if ($response->getStatusCode() === 200) {
    $responseObj = json_decode($response->getBody()->getContents(), true);
    
    print_r($responseObj);
} else {
    echo "Error: " . $response->getStatusCode();
}

For more details on how to use each endpoint, refer to the PerplexityAI API documentation, and the examples provided in the repository.
