Actually, reading this I think you are talking about getting a tourist visa to the Philippines - which is easy as millions of tourists each year find out, so no worries there!
The problem arises only if she wants to visit you in the UK. I do not agree with using a fiancee visa for a visit. A fiancee visa is there if you intend to get married when she is in the UK. You are breaching the terms of the visa if you have no intention of getting married, and this could mean that she will never be granted a visa again.
I also agree that getting a vv is difficult - and impossible if she does not have a decent job in the Philippines.
Therefore, the only solution is for you to visit her, and then apply for a fiancee visa if you decide for certain to get married.
Good luck!
