But when there is capturing group at the end of the pattern and it is not matched, $matches does not contain its index. Test script: --------------- $regexp = '/foo( bar)?/'; preg_match($regexp, 'foo', $matches); print_r($matches); Expected result: ---------------- Array ( [0] => foo [1] => ) Actual result: -------------- Array ( [0] => foo ) ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=67520&edit=1
