Deja Vu!

<?php
if (!preg_match('/^[0-9]+$/', $input)){
  die("invalid input\n");
}
$input = (int) $input;
switch (true){
  case $input < 0: die("invalid input\n"); break;
  case $input <= 15: echo "image 1 to 15\n"; break;
  case $input <= 30: echo "image 16 to 30\n"; break;
  default: die("invalid input\n"); break;
}
?>

If this is homework, you'd better go hire a tutor NOW, because it
ain't gonna get any easier than this...
