I would like to store a few extra details for my custom post type, using meta boxes. Should I store all the values under one meta key in an array, or create several meta key and value pairs?

If you want to use the values to sort or filter the data, you should keep them as separate entries.

and if not, I should use an array? Does it improve performance or have any other benefit?– urok93Commented Aug 20, 2012 at 13:18

2meta data are intended to be discrete key => value pairs. You should store them as such. You gain no performance improvements by trying to force them into an array. Commented Aug 20, 2012 at 16:03
