Как включить стволовый язык в php?

Question

Я установил портер стеммер:

pecl install stem

...

Compile Danish stemmer? [yes] : n
Compile Dutch stemmer? [yes] : n
Compile English stemmer? [yes] : y
Compile Finnish stemmer? [yes] : n

Compile Italian stemmer? [yes] : y

Compile Russian (UTF8) stemmer? [yes] : y
Compile Spanish stemmer? [yes] : n
Compile Swedish stemmer? [yes] : n
Compile Turkish (UTF8) stemmer? [yes] : n

я добавил

extension=stem.so

строка в конце файла php.ini и...

service apache2 restart

Но phpinfo показывает мне:

stem

version     1.5.1

... а функция stem_english не существует.

Как включить языки?

PS: И этот текст я должен вставить, чтобы избежать ошибки "похоже на код". Модераторы могут удалить это.

Answer 1

А-ха-ха, я должен набрать "да" или "нет", а не "у" или "н". Решение:

pecl stem uninstall 
pecl stem install
