FAQ
Example:
In general, it is recommended to use always a project to download your libraries. In an application normally there is more than one library needed.
- Some hosting areas are not accessible by a terminal or SSH. Then it is not possible to use Composer.
- To use Composer is sometimes complicated. Especially for beginners.
- Composer needs much resources. Sometimes they are not available on a simple webspace.
- If you are using private repositories you don't need to share your credentials. You can set up everything on our site and then you provide a simple download link to your team member.
- Simplify your Composer build process. Use our own command line tool to download the vendor folder as binary. This makes your build process faster and you don't need to expose your credentials for private repositories.
Informations about the package phpopenai
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:
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.
Here's an example code that shows you how to use the OpenAI API in PHP:
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:
You can put the variable in Apache configuration file :
And then restart the service.
Now, you can use the environment variable by calling the getenv() function of PHP.
Manage the organization
If you wish to provide information about your organization, you must proceed as follows.
Manage the API's Url
If you need to modify the API's URL, you can proceed as follows:
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.
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.
If you are using the CurlResponse object, you can check that an error has occurred using the validators.
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.

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.
