Not sure about the direct call with curl but the library worked for me, using gpt-4-turbo-preview, and adding a 'tools' param into args for $open_ai->chat(). You need to be real careful with the JSON If using json_decode as it will silently fail on JSON errors unless you specifically check:

$jData = stripslashes(html_entity_decode($tools));
$toolsO = json_decode($jData,true);
if ($toolsO === null && json_last_error() !== JSON_ERROR_NONE){
echo '{"success":false,"message": "OpenAI tools JSON parse fail:'.json_last_error().'"}';
exit;
}
