Experimental PHP OpenAI Responses Client

This is an experimental PHP client for the new OpenAI Responses API. It implements the create, find, delete and list input items methods from the API, returning mapped response objects for seamless integration.

The goal of this experimental client is to provide a quick, easy-to-use library that allows you to experiment with the new endpoints from early on.

Installation

Install the package via Composer:

composer require assistant-engine/php-openai-client

Usage

Conversation State

use AssistantEngine\OpenAI\Client;

$client = Client::make($_ENV['OPEN_AI_KEY']);

$response = $client->responses()->create([
    'model' => 'gpt-4o',
    'input' => "Can you recommend me what I can eat today?"
]);

print_r($response->getOutputText());

$response2 = $client->responses()->create([
    'model' => 'gpt-4o',
    'previous_response_id' => $response->id,
    'input' => "maybe Pizza?",
]);

print_r($response2->getOutputText());

File Search

use AssistantEngine\OpenAI\Client;

$client = Client::make($_ENV['OPEN_AI_KEY']);

$response = $client->responses()->create([
    'model' => 'gpt-4o',
    'tools' => [
        [
            'type' => 'file_search',
            "vector_store_ids" => ["vs_123456789"]
        ]
    ],
    'input' => "when is the event in berlin happening?"
]);

print_r($response->getOutputText());

Web Search

use AssistantEngine\OpenAI\Client;

$client = Client::make($_ENV['OPEN_AI_KEY']);

$response = $client->responses()->create([
    'model' => 'gpt-4o',
    'tools' => [
        [
            'type' => 'web_search_preview'
        ]
    ],
    'input' => "what was a positive news story from today?"
]);

print_r($response->getOutputText());

Computer Use

use AssistantEngine\OpenAI\Client;

$client = Client::make($_ENV['OPEN_AI_KEY']);

// Path to your image file
$imageFilePath = './path/to/browser_screenshot.png';

// Read the image file contents
$imageData = file_get_contents($imageFilePath);

// Base64 encode the image data
$base64Image = base64_encode($imageData);

$response = $client->responses()->create([
    'model' => 'computer-use-preview',
    'tools' => [
        [
            'type' => 'computer_use_preview',
            "display_width" => 1024,
            "display_height" => 768,
            "environment" => "browser"
        ]
    ],
    'input' => [
        [
            "role" => "user",
            "content" => [
                [
                    "type" => "input_text",
                    "text" => "Can you find me products in sale?"
                ],
                [
                    "type" => "input_image",
                    "image_url" => "data:image/png;base64," . $base64Image
                ]
            ]
        ],

    ],
    "truncation" => "auto"
]);

print_r($response);

List input items

use AssistantEngine\OpenAI\Client;

$client = Client::make($_ENV['OPEN_AI_KEY']);
// Define query parameters for pagination and ordering
$params = [
    'after'  => 'item-id-to-start-after',  // Optional: list items after this ID
    'limit'  => 50,                        // Optional: limit number of items (default is 20)
    'order'  => 'desc',                    // Optional: order items in descending order
];

$respId = "resp_123456789";
$list = $client->responses()->inputItems()->list($respId, $params);

print_r($list);

Please note that this is an experimental client with the purpose to give you a fast possibility to explore the new OpenAI responses API with PHP. Please expect bugs and that not every feature from the new API is implemented.
