are there examples for keywords-/tags-using - with different plugins?

You don't need to do that ob_start etc. You can do this instead:

PHP Code:

$keywords = get_page_meta_keywords(false); 


For an array of tags you can do something like:

PHP Code:

$keywords = get_page_meta_keywords(false);
$keywords_array = array_map('trim', explode(',',$keywords));
