Then simply pass in the local file-name (that you want to save it as) and the remote feed:

```php
$feed_cache = new FeedCache('local_file.xml', 'http://example.com/feed.xml');
$feed_cache = new FeedCache('http://example.com/feed.xml');
$data = simplexml_load_string($feed_cache->get_data());
```

You will also need to make sure you have a writable folder called "cache" in the root of your site.

The local filename is hashed string, which represents remote URI, you can specify used algorithm from __construct() method inside FeedCache class.

```php
/* http://php.net/manual/en/function.hash.php */
$this->local = ROOT . 'cache/' . hash('md4', $remote);
```
