<?php 
$db_name = "db"; 
$connection = mysql_connect('localhost','root','') or die(mysql_error()); 
$db = mysql_select_db($db_name,$connection) or die(mysql_error()); 
$sql = "SELECT customer_name,id from customers ORDER BY customer_name desc"; 
$result = mysql_query($sql,$db) or die(mysql_error()); 
if(mysql_num_rows($result)>=1){ 
    $form = '<form method="POST" action=""> 
    <p>Customer name:<select size="1" name="customer">'; 
    while ($row = mysql_fetch_array($result)) { 
     $form .='<option value="'.$row['id'].'">'.ucwords($row['customer_name']).'</option>'; 
    } 
    $form .=' </select></p><p><input type="submit" value="Submit"></p></form>'; 
} 
echo $form;
