what's the php code url for "my profile"?

[kyokushin4life]

Could anyone tell me the code to view "My profile"? The page is different from a page for control panel.

An example is in vbulletin.org's nav bar where you can select "my profile" under "User CP". What's the php code(URL) so that one can view his/her profile?

I tried the following code but doesnt work.
member.php?u=[userid]

In a template:
member.php?u=$bbuserinfo[userid]
In a plugin/file
'member.php?u=' . $vbulletin->userinfo['userid'];
