 * Hi,
 * This is the code
 *     ```
       if ( ( $popular = get_transient( $gabfire_popular_week ) ) === false ) {
       	$popular = stats_get_csv( 'postviews', 'days=7&limit=10' );
       	set_transient('popular_week', $popular, 300);
       }
       ```
   
 * I tried
    if(isset($popular) && is_array($popular) && count($popular) > 0)
 * as well as **isset** and **empty **functions but nothing helped. I do keep getting
   Undefined Variable $popular issue?
 * Anyone can suggest a way to use that code which would prevent that warning?
