Unable to fetch MySQL row data using PHP Program

Question

I am trying for a workable program in which data should be fetched based on input ids and should be save as csv file format. Based on other's question, I wrote program but why it does not fetch the data?

<?php

   header("Content-type: text/csv");
   header("Content-Disposition: attachment;filename=file.csv");
   header("Pragma: no-cache");
   header("Expires: 0");

   $dbc = "mysql:host=localhost;dbname=experiment";
   $user = "katiee";
   $pass = "******";

   $dbo = new PDO($dbc, $user, $pass);
   $sql = "SELECT * FROM clone WHERE id='001'";
   $qry = $dbo->prepare($sql);
   $qry->execute();
   var_dump($qry->fetch(PDO::FETCH_ASSOC));

   $data = fopen('file.csv', 'w');

   while ($row = $qry->fetch(PDO::FETCH_ASSOC))
   {    
      fputcsv($data, $row);
   }
?>

Answer 1

I think there is no record asociated with id='001' . Try with "1".
