```
$meta = get_post_meta($post_id,'',true);

```

brings back all the meta values for $post\_id but it returns an array for each value, as shown below:

I might expect this if I had set the third parameter - single - to false but it's set to true. I haven't found anything in the codex that talks about what exactly is returned when key is blank.

Does someone have to information here and know how I can get back all the keys with each key value being a single value instead of an array of values?
