PHP对接chatGPT代码，openai接口对接，php 实现chatGPT功能

前面已经说过了如何对接chatGPT的接口，下面是PHP的代码版本

<?php
define('OPENAI_API_KEY', '你的API KEY');
$prompt = $_GET['prompt'];
$response = sendPostRequest($prompt);
echo $response;

function sendPostRequest($prompt) {
    $curl = curl_init();

    curl_setopt_array($curl, array(
      CURLOPT_URL => "https://api.openai.com/v1/completions",
      CURLOPT_RETURNTRANSFER => true,
      CURLOPT_ENCODING => "",
      CURLOPT_MAXREDIRS => 10,
      CURLOPT_TIMEOUT => 0,
      CURLOPT_FOLLOWLOCATION => true,
      CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_1_1,
      CURLOPT_CUSTOMREQUEST => "POST",
      CURLOPT_POSTFIELDS => json_encode(array(
          "prompt" => $prompt,
          "max_tokens" => 2048,
          "model" => "text-davinci-003"
      )),
      CURLOPT_HTTPHEADER => array(
        "Content-Type: application/json",
        "Authorization: Bearer " . OPENAI_API_KEY
      ),
    ));

    $response = curl_exec($curl);

    curl_close($curl);
    return $response;
}
?>
