Philippine gf want to visit me in the UK, what type of visa does she need to get?

[njviln]

I am a UK national and me and my girlfriend from the Philippines wants to visit me in the UK for the 6 months allowed, but we cant seem to find which visa she needs to apply to get.

Of course i will pay for all her needs in the UK and also pay for her ticket, there is no problem in that, but UK government websites can be a bit confusing.
