Exercise : Prize (by Michael Beswetherick)

prize.php is a travel site. We want roughly every 10th visitor to win a "free trip". (sample solution)

• Every time the page loads, there should randomly be a 1-in-10 chance that the viewer wins a prize.
• If the user wins, show a congratulation message.
• Use a cookie to remember whether the current user has won the prize. If so, on all future page visits give them a link to redeem their prize.
• Give the user 24 hours to redeem the prize before the cookie expires. (Test it with very small values such as 10 seconds.)
