F - Countdown

Create a Rocket Countdown website that counts down from a number entered by the user.

The website should:

  • Ask the user to enter a starting number
  • Send the number to countdown.php using the POST method
  • Retrieve the starting number using $_POST
  • Use a WHILE loop to count down
  • Display each number on the page
  • Reduce the number by 1 each time the loop repeats
  • Display LIFTOFF! when the countdown reaches zero
  • Include a Back link to start another countdown
$number = $_POST["number"];

while ($number > 0)
{
     echo "<p>$number</p>";
     $number--;
}

while repeats the code inside the { } while the condition is true.

$number– subtracts 1 each time the loop repeats.
