Class?

[BrandonCTW]

I'm very new to PHP so please forgive my foolishness!

I'm getting this error:

[16-May-2023 18:20:00 Europe/Berlin] PHP Fatal error:  Uncaught Error: Class "OpenAI\OpenAI" not found in /Applications/XAMPP/xamppfiles/htdocs/contentapp/chatgpt.php:8
Stack trace:
#0 {main}
  thrown in /Applications/XAMPP/xamppfiles/htdocs/contentapp/chatgpt.php on line 8

Here is my full code:

<?php
	require 'vendor/autoload.php';

	$apiKey = 'MY API KEY'; // Replace with your API Key.

	$openai = OpenAI\Client::create($apiKey);

	if ($_SERVER["REQUEST_METHOD"] == "POST") {
	    $input_text = $_POST['input_text'];
	    $data = [
	        'model' => 'text-davinci-003', 
	        'prompt' => $input_text, 
	        'max_tokens' => 150
	    ];
    
	    $result = $openai->completions()->create($data);

	    echo $result['choices'][0]['text'];
	}

Any thoughts that might help me figure out where I'm going wrong?

Try chaging

$openai = OpenAI\Client::create($apiKey);

to

$client = OpenAI::client($apiKey);

Thank you Phil! I tried that and got a different error:

[16-May-2023 20:10:15 Europe/Berlin] PHP Fatal error: Cannot declare class OpenAI, because the name is already in use in /Applications/XAMPP/xamppfiles/htdocs/contentapp/vendor/openai-php/client/src/OpenAI.php on line 8

ChatGPT was telling me to find where else OpenAI is declared, but I can't seem to find that myself. I might have installed OpenAI-php incorrectly, or more than once. Would that cause the problem?

Try deleting vendor directory and re-running composer install

That appears to have installed correctly...

Same error though:

Guessing the other openai/openai package may have a conflicting class. You can try composer remove openai/openai
