I have one table configuration_variables(name,value). It contains configuration variables for my symfony-application such as reset-password-link-expiration-time. Since these configuration variables change rarely, I want to cache it in a temporary folder (app/cache is the right place?).
How can I do it in symfony2?
I tried How to cache in Symfony 2?. But I think it is not suitable to my reqiuirement.
You could create a cache warmer http://blog.servergrove.com/2012/04/18/how-to-create-a-cache-warmer-in-symfony2/ to cache the configuration in a file. You could use http://php.net/manual/fr/function.var-export.php to export the data to the file, or serialize.
Then, create a service that uses the data from the file.
For such small things you should think about using Redis for your needs. Saving such data in files is bad habit, and Redis offers you great speed for working with data storage.
Redis is an open source, advanced key-value store. It is often referred to as a data structure server since keys can contain strings, hashes, lists, sets and sorted sets.
You can also use SncRedisBundle in pair with it.
