Hi Mahmoud, you have to use the isset() function to check if the key exists within the $facts array. I'm not sure why you are sorting the array, maybe best to remove the sort. For some reason your loop starts at 0 when it should start at 1.

for ($i = 1; $i <= 100; $i++) {
  echo $i;
  if (isset($facts[$i])) {
    // echo out fact here
  }
}
