Retrieve content from the cache or, if it doesn't exist, execute $callback and its result is returned then saved

• $key (string)(Required) Unique cache key to use
• $callback (callable)(Required) Function that returns data to store
• $expiration (int)(Optional) Number of seconds before entry expires. Default 0 (forever)

Retrieve and delete the cache

• $key (string)(Required) Unique cache key to use
• $default (mixed)(Optional) To return if cache doesn't exist. Default null

Like remember but, uses the file contents and no expiration, automatically updates if the file is modified instead

• $key (string)(Required) Unique cache key to use
• $path (string)(Required) Path of the file to read

Support for soft-expiration, Cache::remember* and Cache::file updates in the background

*Except for using anonymous function as callback (closure)
