This example demonstrates asking a two-part question that should cause the AI to respond with two tool call requests. PHP Extension

<?php

include("chilkat.php");

$success = false;

// ----------------------------------------------------------------------------------
// The Javascript file loaded here is shown at the bottom of this page.
// -----------------------------------------------------------------------------------

// Load JavaScript containing the tool functions.
$sbJs = new CkStringBuilder();
$success = $sbJs->LoadFile('qa_data/js_tools/toolset_6.js','utf-8');
if ($success == false) {
    print $sbJs->lastErrorText() . "\n";

// The provider can be "openai", "google", "claude", "grok", "mistral", "custom", etc.
$ai->put_Provider('openai');
// Use your provider's API key.

// Choose a model.

// Send inputs, tool functions, etc. and ask for a "text" response.
// If the AI responds with tool calls, Chilkat automatically handles them by calling your JavaScript
// tool functions as directed by the AI, and sending results back to the AI until the final
// response is received.
