Bug description: preg_split() swallows part of the string
Description:
------------
The following example code shows how preg_split() - when used with
PREG_SPLIT_NO_EMPTY - omits pieces which aren't empty. The returned array
SHOULD contain ALL of the characters from the original string minus the
characters that match the separator. In my example, the separator is a
zero-width match.
I notice that this problem was reported as Bug #15413 before and marked
"Bogus". My example shows that the bug is real.
Reproduce code:
---------------
<?
header ('Content-type: text/plain');
var_export (preg_split ('/\b/', 'a\'', -1, PREG_SPLIT_NO_EMPTY));
?>
Expected result:
----------------
array (
0 => 'a',
1 => '\'',
)
Actual result:
--------------
array (
0 => 'a',
)
