OpenAI PHP是一个增强的 PHP API 客户端，允许您与Open AI API进行交互。

开始
需要PHP 8.1+

首先，通过Composer包管理器安装 OpenAI ：

composer require openai-php/client
然后，与 OpenAI 的 API 交互：

$client = OpenAI::client('YOUR_API_KEY');

$result = $client->completions()->create([
'model' => 'davinci',
'prompt' => 'PHP is',
]);

echo $result['choices'][0]['text']; // an open-source, widely-used, server-side scripting language.
用法
Models资源
list
列出当前可用的模型，并提供有关每个模型的基本信息，例如所有者和可用性。

$response = $client->models()->list();

$response->object; // 'list'

foreach ($response->data as $result) {
$result->id; // 'text-davinci-002'
$result->object; // 'model'
// ...
}

$response->toArray(); // ['object' => 'list', 'data' => [...]]
retrieve
检索模型实例，提供有关模型的基本信息，例如所有者和权限。

$response = $client->models()->retrieve('text-davinci-002');

$response->id; // 'text-davinci-002'
$response->object; // 'model'
$response->created; // 1642018370
$response->ownedBy; // 'openai'
$response->root; // 'text-davinci-002'
$response->parent; // null

foreach ($response->permission as $result) {
$result->id; // 'modelperm-7E53j9OtnMZggjqlwMxW4QG7'
$result->object; // 'model_permission'
$result->created; // 1664307523
$result->allowCreateEngine; // false
