Question

I am searching and trying to learn Alchemy API. However, I am not able to use that API with PHP. Can anybody tell me how to use this API? For instance I would like to categorize the text so I will use textGetCategory PHP method. How to use this method in my PHP files I want to know this.
Thanks.

I have a simple wrapper around the APIs they provide via their PHP classes, maybe you can start from this code and add the methods that you require.

class SimpleAlchemyAPI {

  protected static $instance = null;

  public static function getInstance() {
    if(is_null(self::$instance)) {
      $class = __CLASS__;
      self::$instance = new $class;
    }

    return self::$instance;
  }

  public $api = null;

  protected function __construct() {
    require_once('./AlchemyAPI.php');
    require_once('./AlchemyAPIParams.php');
    $this->api = new AlchemyAPI;
    $this->api->setAPIKey("your_api_key");
  }

  public function getTitle($url) {
    $result = json_decode($this->api->URLGetTitle($url, 'json'), true);
    return $result['status'] == 'OK' ? $result['title'] : null;
  }

  public function getContent($url) {
    $result = json_decode($this->api->URLGetText($url, 'json'), true);
    return $result['status'] == 'OK' ? $result['text'] : null;
  }
}

Just change the paths in the __construct as well as adding your API key and you’re set to use it.

SimpleAlchemyAPI::getInstance()
