# Using an array in query_posts

 * Hi – I am using the following to generate a list of posts that have certain tags:
 * `$query = array('cat' => '4', 'orderby' => 'rand', 'tag__in' => array(7,9))`
 * This works great.
 * The problem is that I can’t seem to generate the array for tag__in dynamically.
   If I use an array of values ( ‘tag__in’ => $array )it always outputs thus:
 * [tag__and] => Array ( [0] => 7,9 )
 * But the query wants only values separated by commas. Because of this it only 
   recognizes the first tag.
 * So how do I make an array only output comma separated values without keys? (PS
   I tried implode() and got the same result).
 * Thanks!

 * Here’s how I got it working:
 *     ```
       $tags = '1,2,3';
       $tags = explode(',',$tags);
       $post_query = array('cat' => '4', 'orderby' => 'rand', 'tag__in' => $tags );
       query_posts($post_query);
       ```
   
 * Here’s what $post_query looks like:
 * Array ( [cat] => 4 [orderby] => rand [tag__in] => Array ( [0] => 7 [1] => 9 ))
 * Maybe it will help someone.
