You have avoided the answer to the question. As I indicated, the problem
with preg_match_all() is that it is unsuitable to the task. Regular
expressions are not suited to parse bracket languages, which are not
regular. PCRE has recursion, but that is limited. And with
preg_match_all() you would have to use alternation where the first match,
not the longest one, would win.
$ php -r 'preg_match_all("/foo|foobar/", "foobar", $matches);
print_r($matches);'
Array
(
[0] => Array
(
[0] => foo
)
)
