Bug description: Strange results with preg_replace using parentheses next to
each other
Description:
------------
I can't tell if this is universal, but with this particular regex it
certainly is a bug. I think it is to do with using parentheses directly
next to each other.
Reproduce code:
---------------
<?
$str = 'arr[sub][sub_sub]';
die(preg_replace('/([^\[\]]*)(.*)/','[\1]\2',$str));
?>
just for the record, this works as expected if i use the pattern:
preg_replace('/([^\[\]]*)\[(.*)\]/','[\1][\2]',$el);
so it appears that the problem is when parenthesised (is that correct?)
expression appear next to each other.
Expected result:
----------------
[arr][sub][sub_sub]
Actual result:
--------------
[arr][sub][sub_sub][]
