flush ( )	Deletes all values from cache.
get ( $id ) : mixed	Retrieves a value from cache with a specified key.
set ( $id, $value, $expire, $dependency = null ) : boolean	Stores a value identified by a key into cache.

Nothing will be done if the cache already contains the key.

public add ( $id, $value, $expire, $dependency = null ) : boolean
return	boolean	true if the value is successfully stored into cache, false otherwise

Deletes a value with the specified key from cache

public delete ( $id ) : boolean
return	boolean	if no error happens during deletion

Be careful of performing this operation if the cache is shared by multiple applications.

public flush ( )

Retrieves a value from cache with a specified key.

public get ( $id ) : mixed
return	mixed	the value stored in cache, false if the value is not in the cache or expired.

If the cache already contains such a key, the existing value and expiration time will be replaced with the new ones.

public set ( $id, $value, $expire, $dependency = null ) : boolean
return	boolean	true if the value is successfully stored into cache, false otherwise
