PHP - Cache arrays saved in included files or not?

Should I 开发者_开发问答use cache to store arrays that are saved in included files? include("filename.php");.. Those included files only have arrays and are about 2 to 5 kilobytes so they are pretty small.

But in term of performance, what is the best? Use cache or simply use include? Just to let you know, I use APC cache.

Thanks for your suggestions!

The arrays hardcoded in those PHP files are already cached, both by APC and probably also by your OS file cache. No need to duplicate it somewhere else.
