MetaDataCacheFile how can I enable it?

[Deep21]

Hello

I added this line 'cache' => new Tonic\MetadataCacheFile( DIR.'/../tmp/tonic.cache'),

and created a file "tonic.cache" but this file is empty.
how can i start using the cache file?

It should just work.

Make sure that the tonic.cache file has the right permissions to be written to by your web server. If you made the file yourself the web server may not have permission to alter it. The MetadataCacheFile class will make the file itself if it doesn't exist as long as it has write permission on the directory.

By default we put the cache file in the /tmp directory since all users have permission to write there.
