Description:
------------
preg_split behaves unexpectet with certain pattern (see reproduce
code):
It returns tripple offsets with the offsetvalue -1.
It gets even worse when you replace:
$reg = "~\{(literal)\}(.*?)\{(/literal)\}|\{(.*?)\}~s";
with
$reg = "~\{\*(literal)\}(.*?)\{(/literal)\}|\{(.*?)\}~s";
it simply returns several off those empty string, offset -1 triples.
P.S.: Hope it is actually a bug and not my ignorance of regex, however
i asked in a forum if anybody knew where the mistake is and i got no
answer and in addition the offset -1 mykes it look like a bug to me.
If it however should be a mistake in my regex it would be kind if you
would let me know how to put it.
Thx in advance
Reproduce code:
---------------
$reg = "~\{(literal)\}(.*?)\{(/literal)\}|\{(.*?)\}~s";
echo $reg.'<br>';
$res = preg_split( $reg, "df{g}s{literal}asd{as}d{/literal}", -1,
PREG_SPLIT_DELIM_CAPTURE|PREG_SPLIT_OFFSET_CAPTURE );
echo '<pre>'.print_r($res, 1).'</pre>';
Expected result:
----------------
~\{(literal)\}(.*?)\{(/literal)\}|\{(.*?)\}~s
Array
(
[0] => Array
(
[0] => df
[1] => 0
)

[0] => s

Actual result:
