//connect to database 
 
$conn = mysqli_connect("localhost", "root", "", "waterdis_stbwd"); 
 
if(mysqli_connect_errno($conn)) { 
 
echo "Unable to connect to database server"; 
 
} 
 

 
//query database for items to populate 
 
$sql = "SELECT id FROM usrs"; 
 
$query = mysqli_query($conn, $sql); 
 

 
echo '<select id="slct">'; 
 
echo '<option value="">Select ID</option>'; 
 
while($id = mysqli_fetch_assoc($query)){ 
 
echo "<option>{$id['id']}</option>";
