See reproduce code.
preg_split in PHP 4.4.8 similarly buggy.

---------------
<?php
$s = " 1 2 3 ";
print_r (preg_split ("/ +/", $s));
print_r (preg_split ("/ +/", $s, PREG_SPLIT_NO_EMPTY));
?>
Expected result:
----------------
Array
(
[0] =>
[1] => 1
[2] => 2
[3] => 3
[4] =>
)
Array
(
[0] => 1
[1] => 2
[2] => 3
)
Actual result:
--------------
Array
(
[0] =>
[1] => 1
[2] => 2
[3] => 3
[4] =>
)
Array
(
[0] => 1 2 3
)
