 * 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](http://codex.wordpress.org/Function_Reference/get_post_meta).

 * Aha, of course. Thank you **very** much!
