Bug description:preg_match recursive does not work with start of subject ^
option
Description:
------------
when i try
php -r 'preg_match("!((\d+)(\s*,\s*(?R))*)$!","22222, 33333, 44444 ,55555
,
abcd,defg,4537, 6537, 8774", $m);echo print_r($m,1);'
Array
(
[0] => 4537, 6537, 8774
[1] => 4537, 6537, 8774
[2] => 4537
[3] => , 6537, 8774
)
Similarly it should work with start of subject ^ option but it does not
work.
It works fine without start of subject ^ option
Test script:
---------------
php -r 'preg_match("!^((\d+)(\s*,\s*(?R))*)!","22222, 33333, 44444 ,55555
, abcd,defg,4537, 6537, 8774", $m);echo print_r($m,1);'
Expected result:
----------------
Array
(
[0] => 22222, 33333, 44444 ,55555
[1] => 22222, 33333, 44444 ,55555
[2] => 22222
[3] => , 33333, 44444 ,55555
)
Actual result:
--------------
Array
(
[0] => 22222
[1] => 22222
[2] => 22222
)
