Sprint comes with two SettingsStores -- one uses the database and the other config files -- but you could easily extend it to create a memcache store for faster storage if your site needed it. Each new Store must extends Myth\Settings\SettingsStoreInterface and implementing the five required methods.


Settings can be organized into groups of items. Typically, these will be module names, but could be for any use. The default group is app which is the generic group used by much of the site's settings. The Interface must find a way to support working with groups of items.

Default Return Value

When a method doesn't have an answer, it should return false. While null might be a more appropriate choice, when dealing with a key/value store like this, it would be valid to have null values stored for items.

Required Methods


Inserts or Updates a single setting item. The first parameter is the key or alias of the item. The second parameter is the $value to set the item to. The third parameter is the group name. The group defaults to 'app'.

public function save($key, $value=null, $group='app');


Retrieves the value for a single item. The first parameter will be the key name. The second parameter is the group name.

public function get($key, $group='app');


Deletes a single key/value pair. This should be a permenant deletion not a "soft delete". The first parameter is the key name. The second parameter is the group.

public function delete($key, $group='app');


Searches the value stores for one with matching requirements. For example, in the database store, you could search by group.

public function findBy($field, $value);


Returns many items. If nothing is passed in as the first parameter, it should return all available configuration values. If a group name is passed as the only parameter, it should return all key/value pairs belonging to that group.

public function all($group=null);
