Assume I\'m in need to loop twice with the result I got form PDO prepared statement.

Answer 1

Your are fecth a row time by time if you need two iteration you should perform a copy eg storing rows

  while ($row = $q->fetch(PDO::FETCH_ASSOC)){
      echo "
" .  $row['user_id'] . "--". $row['fname']. "
";
      $my_rows[] = $row;
  }



   // second loop  this loop will NOT echo any thing ?!
  foreach($my_rows as $key=>$value){
            echo "
" .  $value['user_id'] . "--". $value['fname']. "
";
  }
