can't enable mysqli extension through php.ini

[manne]

Greetings,

i need to enable the mysqli extension in plesk 7.6.1; i added the line "extension=php_mysqli.dll" in the 3 php.ini files that i found in my hdd

c:\windows\php.ini
c:\swsoft\plesk\admin\php.ini
c:\swsoft\plesk\...\horde\php.ini

after that i rebooted the server, but the system ignores my modification, and mysqli doesn't work

i think that the 3 php.ini that i found are "false" php.ini, they are not the php.ini that iis uses, because if i remove them and restart iis, php just keep working (!) but phpinfo() reports some nonsenses like:


Configuration File (php.ini) Path C:\WINDOWS
extension_dir c:\php4 c:\php4


php is running as isapi extension.



what should i do?

thanks!
