				__construct( string $path )

Constructor.


				
				 public 
				
				

				store( string $key, mixed $value, string $ttl = 0 )

$key: Store the variable using this name. keys are cache-unique, so storing a second value with the same key will overwrite the original value.
$value: The value to store.
$ttl: Time To Live; store value in the cache for ttl seconds. After the ttl has passed, the stored value won't be available for the next request. If no ttl is supplied (or if the ttl is empty), the value will persist until it is removed from the cache manually, or otherwise fails to exist in the cache.
