Description:
------------
This may not be a bug, but I would assume with the change in PHP5 (from PHP4) where character access in strings is now done using array operators that count('anystring') would return the length of the string (being the number of array items in the string). I don't see any official documentation on the reasoning for moving to array access operators with strings in PHP5, but I've seen a number of reports that it was for the movement of treating strings as arrays.
