Hi.
I think the 'range()' function should return an array with strings, if the 'start' and 'limit' arguments are numeric strings. Otherwise it should be mentioned in the documentation.

Test script:
---------------
<?php
var_dump(range('0', '9'));

Expected result:
----------------
array(10) {
  [0]=> string(1) "0"
  [1]=> string(1) "1"
  [2]=> string(1) "2"
  [3]=> string(1) "3"
  [4]=> string(1) "4"
  [5]=> string(1) "5"
  [6]=> string(1) "6"
  [7]=> string(1) "7"
  [8]=> string(1) "8"
  [9]=> string(1) "9"
}

Actual result:
--------------
array(10) {
  [0]=> int(0)
  [1]=> int(1)
  [2]=> int(2)
  [3]=> int(3)
  [4]=> int(4)
  [5]=> int(5)
  [6]=> int(6)
  [7]=> int(7)
  [8]=> int(8)
  [9]=> int(9)
}
