   get_post_meta does not act as the reference (http://codex.wordpress.org/Function_Reference/get_post_meta) is telling me:

   The $single parameter acts the opposite as statet. If I set it to TRUE and I expect the value to be an array, I receive an array, if I set it to FALSE, there is something empty beeing returned.

   Actually I might be ment the other way arround. Nevertheles it is strange...

   Wrong. Note the third parameter: $single.
   If you want only a single value returned, use TRUE, else use FALSE for an array of values.

   Don't get it. I store an php array with update_post_meta and I want to get an array back. Then I have to use TRUE, eventhoug
   

   use FALSE for an array

   ...
   What array is meant?

   Have a look at http://codex.wordpress.org/Function_Reference/post_meta_Function_Examples It might explain it better than I could in English :-)
