### Initialize and Use Tuya Cloud Library

Source: https://github.com/aymkdn/tuyacloud-php/blob/master/README.md

Demonstrates how to initialize the TuyaCloud library with API credentials and base URL, and then use it to get device status, send commands, retrieve scenes, and start a scene. Includes error handling for API requests.

```php
<?php
require 'TuyaCloud.php';

$options = [
  'baseUrl' => 'https://openapi.tuyaeu.com', // URL API of Tuya
  'accessKey' => 'nhepe4mrrtz8wju45mk3', // access key of your app
  'secretKey' => 'sf94ryyrfvg3awvg4174m88wjpksytre', // access secret of your app
];

$tuya = new TuyaCloud($options);
try {
  // to get the device status
  // you must pass the device_id
  $response = $tuya->getDevice('bfa18afnfyre87eb7ne0');
  echo '<pre>';
  print_r($response);
  echo '</pre>';
  
  // to send a command 
  // you can pass a JSON string: '{"commands":[{"code":"switch_led","value":true}]}'
  // or a strClass object
  // or an array like the below one:
  $commands = [
    "commands" => [
      [
        "code" => "switch_led",
        "value" => true
      ]
    ]
  ];
  $response = $tuya->setDevice('bfa18afnfyre87eb7ne0', $commands);
  
  // we can retrieve all the scenes (including their id)
  $response = $tuya->getScenes();
  echo '<pre>';
  print_r($response);
  echo '</pre>';
  
  // and we can start a scene
  $response = $tuya->startScene('the_scene_id');
} catch (Exception $e) {
  echo 'Error: ' . $e->getMessage();
}
?>
```
