This loop is going to try to traverse to $arr[26] which does not exist. The last element is at index
number 25. We can fix this with a minor edit:
for ($i = 0; $i < count($arr)-1; i++) {
------------------------------------------------
That is incorrect. Even if count IS 26 it won't traverse it because you arre using the <
operator. Think about it : 26 is NOT less than 26...
