Description:
------------
The code and results attached show two examples of preg_* demonstrating
how an optional parenthesis match at the end of a regular expression is
not being captured if the optional condition is not matched.
I think this is a bug, because if the optional parenthesis is not the
last one in the regex, the empty value IS captured - which suggests that
it should not be omitted just because it happens to be the last one.
Reproduce code:
---------------
preg_match_all("/(1)(23)?/", "12314123", $match, PREG_SET_ORDER);
print_r($match);
print_r(preg_split("/(1)(23)?/", "12314123", -1,
PREG_SPLIT_DELIM_CAPTURE));
Expected result:
----------------
Array
(
[0] => Array
(
[0] => 123
[1] => 1
[2] => 23
)
[1] => Array
(
[0] => 1
[1] => 1
[2] =>
)
[2] => Array
(
[0] => 123
[1] => 1
[2] => 23
)
)
Array
(
[0] =>
[1] => 1
[2] => 23
[3] =>
[4] => 1
[5] =>
[6] => 4
[7] => 1
[8] => 23
[9] =>
)
Actual result:
--------------
Array
(
[0] => Array
(
[0] => 123
[1] => 1
[2] => 23
)
[1] => Array
(
[0] => 1
[1] => 1
)
[2] => Array
(
[0] => 123
[1] => 1
[2] => 23
)
)
Array
(
[0] =>
[1] => 1
[2] => 23
[3] =>
[4] => 1
[5] => 4
[6] => 1
[7] => 23
[8] =>
)
