add_function parameters are strings and not arrays

[epareja2]

Hello, thank you for this library and I'm new to this ChatGPT API.
I'm trying to create a class for defining funtions like this

class myFunctionsClass {
protected ChatGPT $chatGPT; // This is your class

/**

• This function do something very cool
• @param $test : string having the result from chatgpt
  */
  public function doSomething(string $test) {
  // do something with $test
  }
  }

In that same class I'm defining a constructor to add the defined functions like this

public function __construct()
{
$api_key = env('OPENAI_API_KEY');
$this->chatGPT = new ChatGPT($api_key);
$this->chatGPT->add_function('doSomething');
}

The line that assigns a function throws an error

App\Libraries\ChatGPT::add_function(): Argument #1 ($function) must be of type callable|array, string given,

What am I doing wrong here?

Thank you and hopefully you can check this.

Regards

Hi! In PHP, you can pass a class method as a callable by creating an array with the first element being the object and the second element being the method to call. So in this case you need to pass the function as [$this, 'doSomething'] to add_function.

$this->chatGPT->add_function( [$this, 'doSomething'] );

However, I didn't take this into account in designing the library, so it didn't work either. I have now updated the library to work with classes as well. You can find an example of this in examples/class_example.php

Note that the method needs to be public so that the ChatGPT library class can call it.
