Why am I not able to change extension_dir

[ssyed]

when I run phpinfo() it always displays "./" as my extension directory, even though I have set it to something else in the php.ini file ... Is there anything I have to do after changing the config file (Re start server or something?) Because when I make changes to it nothing happens. I have display_errors set to "On" and yet it does nothing I have to manually call ini_set("display_errors",1) before it actually displays errors.

It's annoying because it won't load/recognize mysqli or other functions which I selected when doing the install (stuff that should work on its own since it was installed!)
What is going on here?

Depends on what webserver you have and how PHP is integrated. If it's via a CGI binary, then no, the changes should be immediate. If it's via the ISAPI filter, then yes, you must restart your webserver.

Also, where did you place the php.ini file? Does phpinfo() show the correct location for it?
