This is the simplest example of using Chilkat with Azure AI Foundry. PHP ActiveX

<?php

$success = 0;

//  This example assumes the Chilkat API to have been previously unlocked.
//  See Global Unlock Sample for sample code.

$ai = new COM("Chilkat.Ai");

//  For Azure AI Foundry we use "custom".
$ai->Provider = 'custom';

//  The base URL format for the Chat Completions API when using the cognitiveservices.azure.com domain is:
//  https://{resource-name}.cognitiveservices.azure.com/openai/deployments/{deployment-id}/chat/completions?api-version={api-version}

//  The string "{deployment}" in the base URL is dynamically replaced with the selected AI model each time a request is sent.
//  In this case, the chosen model (below) is "gpt-5.6-terra".  After substitution the base URL becomes: 
//  https://chilkat.cognitiveservices.azure.com/openai/deployments/gpt-5.6-terra/chat/completions?api-version=2025-01-01-preview

//  In this example, our resource name is "chilkat", and the api-version is "2025-01-01-preview"
$ai->BaseUrl = 'https://chilkat.cognitiveservices.azure.com/openai/deployments/{deployment}/chat/completions?api-version=2025-01-01-preview';
$ai->ApiSpec = 'ChatCompletions';

//  Use your provider's API key.
$ai->ApiKey = 'MY_API_KEY';

//  Choose a model.
$ai->Model = 'gpt-5.6-terra';

//  Add a text input.
$ai->InputAddText('Say Hello.');

//  Ask the AI for text output.
$success = $ai->Ask('text');
if ($success == 0) {
    print $ai->LastErrorText . "\n";
    exit;
}

//  Get the text response.
$sbResponse = new COM("Chilkat.StringBuilder");
$ai->GetOutputTextSb($sbResponse);
print $sbResponse->getAsString() . "\n";

//  Sample output:
//  Hello! How can I assist you today?
