I Googled is_sidebar_active(), used by several WordPress trainer, but I came to the decision, the function's surely deprecated. But unfortunately I found no mention, even no entry in WordPress Codex.

As a Wikipedian, I also edit the Codex sometime, but need the confirmation that, is_sidebar_active() IS DEPRECATED, and is_active_sidebar() is ON now.

I used is_active_sidebar() instead of is_sidebar_active() in my theme and it's working fine.

But I need a confirmation. Anybody?

is_sidebar_active() is not a WordPress function. Do not use that. This is probably a typo.

The correct name is is_active_sidebar($index), and that function is not deprecated.

It does appear to be deprecated -- but the only solid reference I found to it was in the Theme Trac site (for instance, http://themes.trac.wordpress.org/ticket/3585 refers to is_sidebar_active() being deprecated). I didn't find is_sidebar_active() in the Core Trac, not even in the search. Google is a little too eager to be helpful, and when I search for is_sidebar_active(), most of the hits I got were for is_active_sidebar() instead.

Long story short, use is_active_sidebar().
