<input type="submit" name="sub" value="calculate">
</form>
</body>

PHP Program to find the even-odd number with a database
<html>

<?php
include 'connection.php';
if(isset($_POST['sub']))
{
$NUM=$_POST['num'];
if($NUM%2==0)
{
mysql_query("insert into even(number) values('$NUM')");
$sel=mysql_query("select * from even");
echo $NUM . " is even";
}
else
{
mysql_query("insert into odd(number) values('$NUM')");
$sel=mysql_query("select * from Odd");
echo $NUM. " is odd";
