Bug description: Recursive Capturing Subpattern
Description:
------------
A recursive subpattern turns out to overwrite data of the previous matched
call... Thus it will only show the last recursive match it made in the
pattern...
Reproduce code:
---------------
$value = 'sub.sub2.sub3.sub4.domain.ext';
if
(preg_match("/^(([a-z0-9]+)(([\.|\-]{1}[a-z0-9]+)|(?R))*\.([a-z]{2,6}))$/i",
$value, $match)) {
print_R($match);
}
Expected result:
----------------
Array
(
[0] => sub.sub2.sub3.sub4.domain.ext
[1] => sub.sub2.sub3.sub4.domain.ext
[2] => sub
[3] => .sub2.sub3.sub4.domain
[4] => .sub2.sub3.sub4.domain
[5] => ext
)
Actual result:
--------------
Array
(
[0] => sub.sub2.sub3.sub4.domain.ext
[1] => sub.sub2.sub3.sub4.domain.ext
[2] => sub
[3] => .domain
[4] => .domain
[5] => ext
)
