I am trying to install intl extension in moodle which is a php application. I've added the lines
extension = php_intl.dll
and
[intl]
intl.default_locale = en_utf8
intl.error_level = E_WARNING
in my php.ini file. When I do this in apache and copy all the icuu*.dll files in apache/bin folder, I can see the extension in the application. In IIS server, I don't know where to copy the icuu*.dll files and whether I need to copy those files. If I restart without copying, the application still runs but I can't see the extension. Can someone please advise me?
