Configuration

The config method is used for configuration, with the first argument being the group name & the second argument as an array to config that group. If the second argument is false or not set, it returns the current config.

The configProp method retrieves a key's value from the config, with the key and group name as parameters.

The default config value is in DEFAULT_CONFIG const.

Currently, there's only one configuration, length_limit, with a default value of -1, which defines the group size. When the item count exceeds this, the first item is removed. -1 means unlimited, also, 0 is currently not useful & should not be used.

Mem::config('default', ['length_limit' => 3]);

Mem::set('item_1', 'value 1');
Mem::set('item_2', 'value 2');
Mem::set('item_3', 'value 3');
Mem::set('item_4', 'value 4');

/*
 * Items in the default group:
 *  [
 *      'item_2' => 'value 2',
 *      'item_3' => 'value 3',
 *      'item_4' => 'value 4'
 *  ]
 */
