Variable $ data. assign a value if it is not defined.
------ Solution --------------------
Check the temporary file ROOT_PATH. '/temp/static_caches/'. $ cache_name. '. php'.
There should be an array of $ data
------ Solution --------------------
Read the cached content, which is the file cache. The cached content is $ data = xxxx.
