# PHPOpenAI
`PHPOpenAI` is a community-maintained library that enables the use of the `OpenAI` API in PHP.
The project is written in PHP and can be used to easily integrate the `OpenAI API` into your existing PHP project.
## System Requirements
This project is based on PHP version 8.1 in order to use features such as enumerations. This project does not require any external dependencies. However, you must have the cURL extension installed for it to work properly.
- PHP version >= 8.1
- cURL extension## Installation
The project uses Composer to manage dependencies. If you haven't already installed Composer, you can do so by following the instructions on the official Composer website.
### Packagist install
To install the project, you can install the package from packagist.org using the following command:
```bash
composer require easygithdev/php-openai
```## Writing a first example
To use the `OpenAI API`, you need to sign up on their website and obtain an API key. Once you have your API key, you can use it in your PHP code to send requests to the OpenAI API.
To find out how to get your key, go to the following address:
[https://help.openai.com/en/articles/4936850-where-do-i-find-my-secret-api-key](https://help.openai.com/en/articles/4936850-where-do-i-find-my-secret-api-key).
Here's an example code that shows you how to use the OpenAI API in PHP:
```php
Completion()->create(
ModelEnum::TEXT_DAVINCI_003,
"Say this is a test",
)->toObject();// Response as stClass object
echo '', print_r($response, true), '';
```This code instantiates a new `OpenAIApi` object with an API key, and then creates a new `Completion` object to perform text completion with the GPT-3 AI language model provided by OpenAI.
The `create()` method is called on the `Completion` object to generate a new text completion. It takes two parameters:
- the first parameter is the ID of the GPT-3 model to use for completion. In this case, it uses the TEXT_DAVINCI_003 model.
- the second parameter is the prompt or input text for which the completion will be generated. In this case, the prompt is "Say this is a test".The result of the completion is returned in the `$response` variable. The result can then be used for further processing, such as displaying the completed text or feeding it into another part of the program for additional processing.
## Manage the API Key
You can use an environment variable to store your key. You can then use this variable as in the following example:
```bash
export OPENAI_API_KEY="sk-xxxxxxxxxxx"
```You can put the variable in Apache configuration file :
```
...
SetEnv OPENAI_API_KEY sk-xxxxxxxxxxx
...```
And then restart the service.
Now, you can use the environment variable by calling the `getenv()` function of PHP.
```php
Completion()->create(
ModelEnum::TEXT_DAVINCI_003,
"Say this is a test",
);
```## Manage the organization
If you wish to provide information about your organization, you must proceed as follows.
```php
completionCreate() , '
';// Passing the router to the client
$response = (new OpenAIClient($apiKey))
->setRoute($route);
```To redefine a route, you need to extend the `OpenAIRoute` class or implement the `Route` interface.
## Manage the reponses
The API returns responses in JSON format. To facilitate access to the different information, you can call `toObject()` or `toArray()` methods of the Handler object to access the data.
```php
Completion()->create(
ModelEnum::TEXT_DAVINCI_003,
"Say this is a test",
)->toObject();// Response as a stClass object
echo '', print_r($response, true), '';$response = (new OpenAIClient($apiKey))->Completion()->create(
ModelEnum::TEXT_DAVINCI_003,
"Say this is a test",
)->toArray();// Response as an associative array
echo '', print_r($response, true), '';
```## Manage the errors
Sometimes, the API returns errors. Therefore, it is necessary to be able to identify what caused the problem. To handle this difficulty, you have many options.
If you are using a Handler object with `toObject()` or `toArray()` methods, just use a `try-catch` structure.
```php
try {
$response = (new OpenAIClient('BAD KEY'))
->Completion()
->create(
ModelEnum::TEXT_DAVINCI_003,
"Say this is a test",
)
->toObject();
} catch (Throwable $t) {
echo nl2br($t->getMessage());
die;
}
```If you are using the `CurlResponse` object, you can check that an error has occurred using the validators.
```php
$handler = (new OpenAIClient('BAD KEY'))->Completion()->create(
ModelEnum::TEXT_DAVINCI_003,
"Say this is a test",
);$response = $handler->getResponse();
$contentTypeValidator = $handler->getContentTypeValidator();if (!(new StatusValidator($response))->validate() or
!(new $contentTypeValidator($response))->validate()) {
echo $response->getBody();
}
```[Learn more about errors](https://platform.openai.com/docs/guides/error-codes/api-errors).
## An example of application
Here is a video showing an application that allows you to create images with a painting style defined by the user.
This application is created using the PHPOpenAI project.https://user-images.githubusercontent.com/3519890/230593418-22f26562-e88c-4a92-9601-93bb671a16c0.mp4
You can find the code here:
[https://github.com/EasyGithDev/PHPOpenAI-Playground.git](https://github.com/EasyGithDev/PHPOpenAI-Playground.git).
## Code samples
Integrating OpenAI into your application is now as simple as a few lines of code.

### Text Completion using ChatGPT
```php
$response = (new OpenAIClient($apiKey))->Chat()->create(
ModelEnum::GPT_3_5_TURBO,
[
new ChatMessage(ChatMessage::ROLE_SYSTEM, "You are a helpful assistant."),
new ChatMessage(ChatMessage::ROLE_USER, "Who won the world series in 2020?"),
new ChatMessage(ChatMessage::ROLE_ASSISTANT, "The Los Angeles Dodgers won the World Series in 2020."),
new ChatMessage(ChatMessage::ROLE_USER, "Where was it played?"),
]
)->toObject();

```php
$response = (new OpenAIClient($apiKey))->Completion()->create(
ModelEnum::TEXT_DAVINCI_003,
"Say this is a test",
)->toObject();
```[Learn more about text completion](https://platform.openai.com/docs/guides/completion).
### Text Completion using stream
The stream attribute in the OpenAI API is an optional parameter that you can use to control the data flow returned by the API. If you set this option to True, the API will return a response as a streaming data rather than a single response.
This means that you can retrieve the results of the API as they become available, rather than waiting for the complete response before processing them. This option can be useful for applications that require real-time processing of large amounts of data.
