<input type="text" name="USD">
<input type="submit" name="sub" value="submit">
</form>
<?php
$sub = $_POST['sub']; // makes a variable from the Posted Data
$USD = $_POST['USD'];
$rate = 46;
if(isset($sub)) // when submit is pressed, this runs
{
$INR = $rate*$USD
echo "The converted dollar is ".$INR;
// if you really wanted to be fancy you could do this:
echo $USD." in Rupee is ".$INR;
}
