Configuration

How to use the Config object

To change the default parameters, you have to use the Config class. Create a new instance and pass it to the Reader object like that:

use PicoFeed\Reader\Reader;
use PicoFeed\Config\Config;

$config = new Config;
$config->setClientUserAgent('My custom RSS Reader')
       ->setProxyHostname('127.0.0.1')
       ->setProxyPort(8118);

$reader = new Reader($config);
...
