   Hello
   When I save an array with get_post_meta I'll get an extra array as this:
   

   Array
   (
       [0] => Array
           (
               [0] => http://www.yahoo.com
               [1] => http://www.internet.com
               [2] => http://www.google.com
               [3] => http://www.cnn.com/
               [4] => http://www.php.net/
           )
   
   )

   So when I gonna write it out I have to write like this:
   

   $a = get_post_meta(1,'my_key');
   
   for($i=0;$i<count($a[0]);$i++) {
       echo $a[0][$i].'<br />';
   }

   Why this?

   Does this change things:

   $a = get_post_meta(1,'my_key',TRUE);

   The TRUE says to return a single value (which for you is an array), not an array of all values for that key (an array of arrays). See the Codex here.

   Aha, of course. Thank you very much!
