<?php
$con=mysqli_connect("localhost","root","","trial");

if (mysqli_connect_errno())
  {
  echo "Failed to connect to MySQL: " . mysqli_connect_error();
  }
if(isset($_POST['submit']))
{
$billno=$_POST['billno'];

$doa=$_POST['doa'];
$dod=$_POST['dod'];
$dbcd=$_POST['dbcd'];
$acno=$_POST['acno'];
$dosub=$_POST['dosub'];
$suby=$_POST['suby'];
$dop=$_POST['dop'];
$credate=$_POST['credate'];
$paytype=$_POST['paytype'];


$sql="UPDATE cust SET doa ='$doa', dod = '$dod', dbcd='$dbcd', acno='$acno', dosub='$dosub', suby='$suby', dop='$dop', credate='$credate' 
  ** WHERE billno = '$billno'";**
print $sql;


if (!mysqli_query($con,$sql))
  {
  die('Error: ' . mysqli_error($con));
  }


}

echo "1 record edited";

mysqli_close($con);
?>

my data base (cus) is not getting updated as the bill no while for WHERE clause gives a blank space before and after the fetched result

After:

if(isset($_POST['submit']))
{

Insert:

$_POST = array_map('trim', $_POST);

If, instead, you want to apply it only to one variable then write only this:

$billno = trim($_POST['billno']);

$result = mysqli_query($con,"SELECT custype,SUM(amt) FROM cust WHERE custype = '$custype' AND DATE(day) >='$from' AND DATE(day) <='$to'");

while($row=mysqli_fetch_array($result))  
{  
echo "<tr>";
