<html lang="en">

<head>

<!--title for web page -->

</tr>

</table>

</form>

display_results.php :

<?php

if(isset($_POST['btnSubmit']))

//taking number of hours worked

$hours=$_POST['txtHours'];

$wages=$_POST['txtWages'];

//checking if $hours is not empty

if($hours=="" || !is_numeric($hours))

{

//display error message

echo "Number of hours can not be empty or can not be alphabets";

}

else if($wages=="" || !is_numeric($wages))

{

//display error message

echo "Hourly wages can not be empty or can not be alphabets";

}

else

{

$grossPay=0;

//calculate gross pay

//checking number of hours

if($hours<=40)

{

//if hours is less than or equal to 40

$grossPay=$hours*$wages;

}

else

{

//if hours are > 40

$grossPay=40*$wages+($hours-40)*(1.5*$wages);

}

//display gross salary

echo "<h1>Employee's weekly gross salary for <br/> Hours : ".$hours." <br/> Hourly Wages : ".$wages."<br/> Gross Salary :".$grossPay."</h1><br/>";
