Please try code given below

if( !empty( $my_var ) ) {
    $meta_counts = array();
    $total_count = 0;  
    foreach( $my_var as $meta_index=>$meta_value ){
         if(isset($meta_index) && !empty($meta_index)){
            $meta_index_arr = explode(',', $meta_index);
            $meta_counts[$meta_index] = count($meta_index_arr);   
            $total_count += $meta_counts[$meta_index];
         }else{
                          $meta_counts[$meta_index] = 0;
        }
     }

}
print_r ($meta_counts);
echo $total_count;
