Description:
------------
In the lastest version of PHP (5.1.2), running str_split with an empty
string returns an array containing a single element, which is also an
empty string. This seems counterintuitive and is a different result
than in previous versions of PHP5. Rather than return a single-element
array with an empty string, I would expect an empty array with no
elements. (5.0.4 evaluates in the latter way - giving the more
intuitive result).
This makes a difference when the resulting array is used as the
argument to foreach, for example, such as foreach(str_split($string) as
$letter). If a string is empty, it would be intuitive that foreach would
never execute its inner code.
If this is an intended behavior, then the version difference ought to
be noted in the documentation. I do think, however, that the old
behavior made more sense.
Reproduce code:
---------------
var_dump(str_split(""));
Expected result:
----------------
array(0) { }
Actual result:
--------------
array(1) { [0]=> string(0) "" }
