How do you load third party package in Codeigniter?

This is elementary question.

I downloaded the Facebook PHP SDK and stored it in "third_party" folder within Codeigniter. I am hoping that is wher开发者_如何学Pythone it should go. But how do you load such PHP SDK?

Thanks

I ended up sticking in in CI's libraries directory and adding it to the libraries autoload in config/autoload.php

autoload.php:

$autoload['libraries'] = array('facebook');

Then, I made a small change to the Facebook implementation itself (constructor of the Facebook class) and added the keys to my app's config file:

public function __construct()
{
    $ci =& get_instance();

    $this->setAppId($ci->config->item('fb_appId'));
    $this->setApiSecret($ci->config->item('fb_secret'));
    $this->setCookieSupport($ci->config->item('fb_cookie'));
    $this->setBaseDomain($ci->config->item('fb_domain'));
    $this->setFileUploadSupport($ci->config->item('fb_upload'));
}

...And presto - you now have access to Facebook's API in your models and controllers via $this->facebook
