set_cache_location()

class SimplePie {
	set_cache_location ( [string $location = './cache'] )
}

Set the file system location (not WWW location) where the cache files should be written.

• Available since SimplePie 1.0.
• Previously existed as cache_location() since SimplePie Preview Release.

Set where the cache files should be stored.

$feed = new SimplePie();
$feed->set_feed_url('http://simplepie.org/blog/feed/');
$feed->set_cache_location($_SERVER['DOCUMENT_ROOT'] . '/app/cache_files');
$feed->init();
$feed->handle_content_type();
echo $feed->get_title();

Unsupported! We've enabled MySQL caching in an experimental branch that will be integrated into a future SimplePie release. If you're using that experimental branch, you can enable database caching as follows:

$feed = new SimplePie();
$feed->set_feed_url('http://simplepie.org/blog/feed/');
$feed->set_cache_location('mysql://username:password@hostname:port/database');
$feed->init();
$feed->handle_content_type();
echo $feed->get_title();
