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;
}
?>
