Laravel - Cache - Incrementing Decrementing Values

The increment and decrement methods may be used to adjust the value of integer items in the cache. Both of these methods accept an optional second argument indicating the amount by which to increment or decrement the item's value:

    
    Cache::increment('key');
    Cache::increment('key', $amount);
    Cache::decrement('key');
    Cache::decrement('key', $amount);
