Добрый день. Столкнулся с тем, что php не воспринимает системные настройки локали:
root@test4:~# locale
LANG=ru_RU.CP1251
LANGUAGE=ru
LC_CTYPE="ru_RU.CP1251"
LC_NUMERIC="ru_RU.CP1251"
LC_TIME="ru_RU.CP1251"
LC_COLLATE="ru_RU.CP1251"
LC_MONETARY="ru_RU.CP1251"
LC_MESSAGES="ru_RU.CP1251"
LC_PAPER="ru_RU.CP1251"
LC_NAME="ru_RU.CP1251"
LC_ADDRESS="ru_RU.CP1251"
LC_TELEPHONE="ru_RU.CP1251"
LC_MEASUREMENT="ru_RU.CP1251"
LC_IDENTIFICATION="ru_RU.CP1251"
LC_ALL=
root@test4:~# php -r "echo (10.10);"
10.1
root@test4:~# php -r "echo setlocale(LC_ALL, 0);"
