I have been trying to utilize OpenAI's Stream Completion feature using the Openai-php SDK in PHP. I am having trouble understanding how to set a variable inside a function. Can anyone help me with this?
Here's the code snippet I am working with:
```php
require 'vendor/autoload.php';
use OpenAI\API;
use OpenAI\OpenAI;
use OpenAI\Engine\Engine;
use OpenAI\APIClient;
use OpenAI\Models\StreamCompletions\StreamCompletionRequest;
function setVariableInsideFunction() {
$variable = 'This is a variable inside the function.';
// How can I pass this variable to the OpenAI Stream Completion request?
// What would be the correct syntax to set it?
}
setVariableInsideFunction();
```
I want to understand how to properly pass the `$variable` inside the `setVariableInsideFunction()` to the OpenAI Stream Completion request. Could someone provide the correct syntax for achieving this?
Please let me know if you need any additional information. Thank you in advance for your help!

Hey there! I faced a similar situation when I was working with the Openai-php SDK for Stream Completion in PHP. Setting a variable inside a function and passing it to the OpenAI Stream Completion request isn't very complex.
In your code snippet, you can define the `$variable` as a global variable outside the function. This way, it will be accessible within the function scope. Here's an example modification:
By using the `global` keyword, you can modify the global variable `$variable` within the function. This modification allows you to access and utilize the variable as required in your OpenAI Stream Completion request.
Feel free to adjust other parameters like the API key, prompt, and engine according to your specific needs. Let me know if you have any further questions!
